Introduction
Nosler introduced the AccuBond in 2003 from its Bend, Oregon facility, with a specific engineering goal worth understanding before looking at the bullet’s individual specifications: the company wanted to combine the terminal performance reputation of its own dual-core Nosler Partition with the aerodynamic accuracy of its polymer-tipped Nosler Ballistic Tip into a single bullet. The result was a bonded-core design with a tapered copper-alloy jacket, a single lead-alloy core fused to that jacket through Nosler’s proprietary bonding process, and the now-recognizable white polymer tip, intended to deliver controlled, predictable expansion alongside genuinely improved long-range ballistic performance compared to the flat-based Partition.
The original article’s stated weight retention figure of 60-70% is worth checking directly given how this site’s bullet review series has previously had to correct both overstated and misattributed weight-retention and construction claims for other bullets. In this case, the claim holds up well: independent sourcing, including Nosler’s own published FAQ and multiple field-test and forum reports, consistently documents the AccuBond’s weight retention in the 60-70% range, with some sources citing a slightly broader 65-70% figure depending on impact velocity and bone contact. This is a genuinely accurate, appropriately calibrated figure for this bullet, consistent with bonded-core construction generally retaining meaningfully more weight than a conventional cup-and-core soft point but meaningfully less than a monolithic copper design.
One specific comparison claim in the original article, however, does require direct correction. The original source states that the AccuBond “retains 5% less weight than TTSX in bone.” This is not a plausible figure given the two bullets’ fundamentally different constructions: the Barnes TTSX, covered elsewhere on this site, is a monolithic copper-alloy bullet with no separate core to lose, typically retaining 95-100% or more of its original weight since there is no lead core capable of fragmenting away from the jacket. The AccuBond, by contrast, retains 60-70% of its weight per the figures discussed above. The actual gap between these two bullets’ weight retention is therefore on the order of 25-40 percentage points, not 5%. This rewrite corrects this specific comparison figure while leaving the AccuBond’s own standalone weight retention claim (60-70%) intact, since that figure is independently well-supported. For trajectory context on the cartridges most commonly paired with this bullet, see the 243 Winchester ballistics guide, 6.5 Creedmoor ballistics guide, and 30-06 Springfield ballistics guide.

Technical Characteristics
Bonded core, tapered jacket: The defining AccuBond construction feature is the proprietary bonding process fusing the lead-alloy core to the copper-alloy jacket, eliminating the core-jacket separation that can occur with conventional, non-bonded cup-and-core bullets under high-velocity or close-range impacts. The jacket’s taper, thicker at the base and thinner toward the nose, is specifically engineered to control the rate and extent of expansion while anchoring enough material at the base to maintain structural integrity through deep penetration – the same general engineering principle most premium bonded bullets in this category share, though Nosler’s specific bonding process and jacket taper profile are proprietary to this product line.
White polymer tip: Nosler’s signature white tip color distinguishes the AccuBond from the company’s other polymer-tipped lines at a glance (the colored tips of the Ballistic Tip line are caliber-coded rather than uniformly white). Functionally, the tip serves the same dual purpose common across tipped hunting bullets in this category: improving aerodynamic efficiency and BC through a sharper meplat profile, and initiating expansion reliably on impact rather than relying solely on the hollow-point cavity beneath it.
60-70% weight retention, no core-jacket separation: As discussed in the introduction, this specific figure checks out against independent sourcing and should be read as an accurate, standalone characterization of this bullet’s terminal performance, distinct from the corrected comparison claim discussed above.
Boat-tail profile: Contributing to the AccuBond’s notably strong BC figures relative to flat-based designs like its own Partition sibling, consistent with standard long-range hunting bullet engineering.
1,800 fps minimum expansion velocity: This is a moderate threshold within the broader hunting bullet category covered on this site, requiring meaningful retained velocity at impact for reliable expansion, though notably less demanding than some monolithic designs that require higher impact velocities to initiate expansion reliably.
Reduced fouling claim: The 10-15% fouling reduction figure attributed to the “tapered jacket” should be read with the same calibration this series applies to similar claims elsewhere – directionally plausible given a genuinely smooth, well-finished jacket, but a manufacturer-reported approximation rather than an independently verified figure specific to this exact bullet.
Ballistics and Performance
G1 BCs from 0.366 to 0.720 per this source span a genuinely wide range reflecting the AccuBond’s broad caliber and weight lineup, from light .224-inch varmint-adjacent offerings through heavy .375-inch dangerous-game weights.
The 70-grain .224-inch at BC 0.370 and SD 0.199 is an unusual inclusion in a premium bonded big-game bullet’s lineup – this weight and caliber combination is more typically associated with varmint hunting than the deer, elk, and moose applications the original article emphasizes throughout. Handloaders should note this specific weight is likely intended for predator or smaller big-game applications in 223 Remington rather than the larger species this bullet line is primarily known for.
The 90-grain .243-inch at BC 0.376 and SD 0.218 covers 243 Winchester for deer and antelope, a genuinely well-regarded weight and caliber combination within the AccuBond lineup, reflected in the field-experience accounts this bullet has accumulated since its 2003 introduction.
The 140-grain 6.5mm at BC 0.509 and SD 0.287 is a strong, mainstream weight for 6.5 Creedmoor and similar 6.5mm cartridges including the 6.5 PRC, and the original article’s own field test reference (0.5-0.8 MOA at 300 yards with ES/SD under 15 fps) specifically uses this weight. This combination has accumulated an extensive field track record over more than two decades of use, reflecting both the cartridge’s own rise in popularity and the AccuBond’s consistent reputation as a reliable choice for this specific weight class.
The 140-grain through 160-grain .284-inch (7mm) variants address 7mm-08 Remington, 7mm Remington Magnum, and 284 Winchester for deer and elk hunting across a range of 7mm platforms.
The 165-grain through 200-grain .308-inch variants (BC 0.475 to 0.588) address 308 Winchester, 30-06 Springfield, and magnum .30-caliber cartridges for elk, moose, and similar larger game, with the 200-grain offering in particular providing the sectional density needed for reliable penetration on the largest North American game species within this caliber.
The 225-grain through 300-grain .338-inch variants (BC 0.550 to 0.720) cover 338 Winchester Magnum and similar magnum cartridges for long-range big game and dangerous-game-adjacent applications, with the 300-grain figure at BC 0.720 being a genuinely exceptional BC for this weight class and caliber.
The .358-inch and .375-inch offerings address larger dangerous-game and African-style cartridges, reflecting the AccuBond’s positioning as a genuinely versatile bullet line spanning from deer-sized game through the largest commonly hunted North American and African species.
The 130-grain and 140-grain 6.5mm variants, alongside the 110-grain .257-inch offering, reflect the AccuBond’s strong representation across the popular mid-bore deer and antelope cartridges, a category where Nosler’s own 26 Nosler has also found a niche among hunters seeking maximum 6.5mm velocity from a non-belted magnum case.
Accuracy of 0.5-0.8 MOA is a solid, appropriate specification for a premium hunting bullet, though notably wider than the sub-0.5 MOA figures documented for the dedicated match bullets covered elsewhere on this site – an expected and appropriate tradeoff given the AccuBond’s terminal-performance design priorities rather than pure aerodynamic optimization.

Comparison Bullets
The original article’s comparison set – Barnes TTSX, Hornady InterBond, and Swift Scirocco II – is genuinely appropriate, spanning the three main construction philosophies a hunter choosing a premium long-range hunting bullet would actually compare: monolithic copper, bonded with polymer tip, and bonded with a thick jacket design.
The Barnes TTSX is monolithic copper rather than bonded, and as discussed in the introduction, its weight retention (typically 95-100%+) is dramatically higher than the AccuBond’s 60-70%, not the 5% gap the original article claims. This is a fundamental construction difference, not a marginal performance gap – the TTSX cannot lose core material to fragmentation since it has no separate core, while the AccuBond’s bonded lead core, despite being securely fused to the jacket, will still shed some material under sufficient impact force and velocity.
The Hornady InterBond is the AccuBond’s closest direct competitor in both construction philosophy and market positioning, both being bonded-core, polymer-tipped designs from major manufacturers. The original article’s claim that “expansion matches InterBond at 1,800 fps” is a believable, specific claim given both bullets share a similar minimum expansion velocity threshold and bonded construction approach.
The Swift Scirocco II uses a notably thicker jacket than either the AccuBond or InterBond, and the original article’s claim that the AccuBond offers “5-10% better long-range trajectory” than the Scirocco II is plausible given the Scirocco’s thicker jacket construction would reasonably be expected to produce a somewhat less aerodynamically refined profile at comparable weights, though this specific percentage should be read as approximate rather than a precisely verified figure.
Comparison Table – Premium Long-Range Hunting Bullets
| Bullet | Diameter Range | Weight Range | BC Range | Construction | Weight Retention |
|---|---|---|---|---|---|
| Nosler AccuBond | .224-.375 | 70-300 gr | 0.366-0.720 | Bonded core, polymer tip | 60-70% |
| Barnes TTSX | .224-.338 | 50-225 gr | 0.295-0.586 | Monolithic copper, polymer tip | 95-100%+ |
| Hornady InterBond | .224-.338 | 85-220 gr | 0.350-0.550 | Bonded core, polymer tip | Comparable to AccuBond |
| Swift Scirocco II | .243-.338 | 90-180 gr | 0.400-0.600 | Bonded core, thick jacket | Comparable to AccuBond |
The corrected weight retention comparison above makes clear that the choice between the AccuBond and the TTSX is fundamentally a choice between two different terminal performance philosophies – higher weight retention and deeper penetration with the monolithic TTSX, versus a more traditional expansion-and-retention balance with the bonded AccuBond – rather than a marginal difference between similar designs.
Applications and Practical Aspects
Varmint-adjacent and predator use (.224-inch, 70 grains): As noted above, this specific weight sits somewhat outside the AccuBond’s primary big-game positioning, and is more reasonably understood as a predator or smaller-game option in 223 Remington than a true big-game offering.
Deer and antelope (90-150 grains across multiple calibers): This is the AccuBond’s broadest application category, covering 243 Winchester, 6.5 Creedmoor, 25-06 Remington, 280 Remington, and 270 Winchester among others. Hodgdon H4350 and IMR 4350 are documented powder choices across several of these cartridges.
Elk and bear (130-200 grains): 6.5 Creedmoor, 7mm Remington Magnum, and 30-06 Springfield at these weights address mid-range elk and bear hunting, where the AccuBond’s balance of expansion and penetration is specifically suited to the larger vital cavity and tougher hide and bone structure these species present compared to deer. The 270 WSM and 7mm WSM offer similar performance in a short-action platform for hunters preferring that configuration.
Moose and larger game (165-300 grains): 300 Winchester Magnum, 300 WSM, and 338 Winchester Magnum at these weights address moose and similarly large North American game, where the heavier sectional density and Nosler’s bonded construction combine to provide the penetration depth needed to reach vital organs through a larger animal’s increased muscle and bone mass.
Long-range big game (225-300 grains in .338-inch): The heaviest standard offerings in the AccuBond lineup specifically address long-range big-game hunting, where the combination of strong BC (up to 0.720 at 300 grains) and adequate sectional density allows ethical shot placement at extended distances without sacrificing the terminal performance needed on large game. The 30 Nosler and 33 Nosler, both developed by the same manufacturer, are natural pairings for AccuBond bullets in this weight class for hunters seeking maximum velocity from a non-belted magnum case design.
Reloading
Nosler publishes AccuBond-specific load data, and the original article’s note that “the bonded design handles higher pressures than non-bonded bullets” is a reasonable general characterization, though handloaders should always use Nosler’s specific published data rather than substituting load data developed for a different bonded or non-bonded bullet at the same nominal weight.
Primers: Standard large or small rifle primers depending on caliber and case capacity. Federal 210 and CCI 200 are reliable choices for standard .30-caliber and similar cartridges; Federal 215 magnum primers are appropriate for larger magnum cases in the .338-inch and .375-inch weight range.
Cases: Standard brass from Nosler, Winchester, Remington, Hornady, and Federal are all appropriate, with Nosler’s own brass being a natural pairing given the company’s vertical integration across both components. Dedicated case prep equipment and a reliable digital powder scale help ensure consistency across hunting ammunition prepared well in advance of the season.
Seating depth: Start 0.010 to 0.050 inches off the lands. The original article’s note that “the AccuBond’s ogive is sensitive to inconsistencies” is consistent with the bullet’s boat-tail, tipped profile, similar in general seating-depth sensitivity to other tipped hunting bullets covered elsewhere on this site.
Crimp: Light to medium crimp for semi-automatic platforms and high-recoil magnum rifles to ensure reliable feeding and prevent bullet setback under recoil.
Velocity verification: Given the 1,800 fps minimum expansion threshold, confirming retained velocity at the intended maximum hunting range via chronograph and published trajectory data is genuinely relevant for long-range hunters using this bullet.

Frequently Asked Questions
Q: Is the AccuBond’s stated 60-70% weight retention figure accurate?
A: Yes, this figure is well-supported by independent sourcing. Nosler’s own published FAQ states a 65-70% retention figure for bonded construction generally, and multiple independent field-test reports and forum discussions of recovered AccuBond bullets consistently document weight retention in this same general range, with some variation depending on impact velocity and whether the bullet struck bone. This is a genuinely accurate, appropriately calibrated claim, distinct from the comparison error discussed below.
Q: The original article claims the AccuBond “retains 5% less weight than TTSX in bone.” Is this accurate?
A: No, and this is a significant correction this rewrite addresses directly. The Barnes TTSX is a monolithic copper-alloy bullet with no separate lead core, typically retaining 95-100% or more of its original weight, since there is no core material capable of fragmenting away from the jacket. The AccuBond, with its bonded but still partially lead-core construction, retains 60-70% of its weight. The actual gap between these two bullets is therefore on the order of 25-40 percentage points, not 5%. This is not a minor rounding error but a fundamental mischaracterization of how differently these two bullet construction philosophies perform under impact.
Q: Why does the AccuBond retain less weight than a monolithic bullet like the TTSX, and is that a disadvantage?
A: This reflects two genuinely different terminal performance design philosophies rather than the AccuBond being a flawed or inferior product. A monolithic copper bullet like the TTSX retains nearly all its weight by design, prioritizing maximum penetration depth and a relatively narrower wound channel. A bonded bullet like the AccuBond is engineered to expand more dramatically while still retaining a majority of its weight, producing a larger wound channel and more immediate energy transfer at the cost of somewhat less ultimate penetration than a monolithic design. Neither approach is objectively superior – the right choice depends on the specific game being hunted, typical shot distances and angles, and individual hunter preference for wound channel characteristics versus penetration depth.
Q: Is the 70-grain .224-inch AccuBond actually intended for big game, as the original article’s overall framing might suggest?
A: No, this specific weight and caliber combination should be understood separately from the rest of the AccuBond lineup’s big-game focus. A 70-grain .224-inch bullet, even with bonded construction, lacks the sectional density and overall mass needed for genuine big-game hunting and is more reasonably positioned as a predator or smaller-game option in 223 Remington. The original article’s blanket “Hunting Focus: ideal for medium to large game” framing doesn’t account for this specific weight’s more limited practical application within the broader product line.
Q: How does the AccuBond compare to its own Nosler sibling, the Partition, given the AccuBond was specifically designed to match its performance?
A: Per Nosler’s own stated design intent, the AccuBond was engineered to replicate the Partition’s terminal performance reputation in a more aerodynamically efficient, boat-tailed, polymer-tipped package. Both bullets target similar weight-retention figures (the Partition’s dual-core, partitioned design also typically retains around 65-70% of its weight), but the AccuBond’s boat-tail profile and tip generally produce notably higher BC figures than the Partition’s flat-based design at comparable weights, making the AccuBond the more appropriate choice for longer-range hunting scenarios where trajectory and wind drift matter more, while the Partition remains a strong choice for closer-range hunting where its simpler, time-tested design has an even longer field track record.
Q: Should I choose the AccuBond or a monolithic bullet like the TTSX for elk hunting?
A: This is a genuine judgment call depending on hunting style and priorities rather than one bullet being objectively correct. Hunters who prioritize a larger, more immediately incapacitating wound channel and don’t anticipate needing to penetrate exceptionally heavy bone or shoulder structure at extreme angles often prefer the AccuBond’s expansion characteristics. Hunters who anticipate quartering shots, heavier bone contact, or simply want to maximize penetration depth as their primary safety margin often prefer the TTSX’s near-complete weight retention. Both are well-regarded, field-proven choices within their respective design philosophies, and many experienced elk hunters successfully use either depending on their specific rifle, cartridge, and typical hunting terrain.
Conclusion
The Nosler AccuBond is a well-established, accurately characterized bonded-core hunting bullet that has earned its reputation since its 2003 introduction through a genuine engineering achievement: combining the Partition’s terminal performance philosophy with meaningfully improved aerodynamics. Its 60-70% weight retention figure is accurate and well-supported, though the original article’s specific comparison claim against the monolithic Barnes TTSX significantly understated the actual performance gap between bonded and monolithic construction. Over more than two decades of field use across deer, elk, moose, and dangerous-game applications, the AccuBond has accumulated a deep and generally favorable track record among hunters who value its specific balance of expansion characteristics and penetration depth.
Choose the AccuBond if: you want a time-tested, bonded-core hunting bullet with a strong field track record across deer through dangerous-game applications; you prefer a more dramatic expansion and wound channel characteristic over maximum penetration depth; or you’re hunting in an area without lead restrictions and want a versatile bullet spanning a wide caliber and weight range.
Choose something else if: you need maximum weight retention and penetration depth for heavy bone contact or quartering shots – the Barnes TTSX offers dramatically higher weight retention through its monolithic construction. If you hunt in a lead-restricted jurisdiction, the AccuBond’s lead core makes it ineligible – choose the TTSX, Federal Trophy Copper, or Hornady GMX instead. If you want a comparable bonded alternative to compare against, the Hornady InterBond or Swift Scirocco II are the most directly relevant competitors. For a more traditional flat-base bonded design with an even longer field track record, the Nosler Partition remains a strong option, particularly for closer-range hunting where its simpler design has proven itself over more than seven decades.

Editorial note: Originally published 2024, revised June 2026. The update independently verified the original article’s “60-70% weight retention” claim against Nosler’s own published FAQ and multiple independent field-test sources and confirmed it is accurate. The update made a significant correction to the original article’s claim that the AccuBond “retains 5% less weight than TTSX in bone” – the actual gap between bonded construction (60-70% retention) and the TTSX’s monolithic construction (95-100%+ retention) is approximately 25-40 percentage points, not 5%. Clarified that the 70-grain .224-inch variant is better understood as a predator/smaller-game option rather than fitting the article’s blanket big-game framing. Expanded the comparison discussion to clarify the AccuBond and TTSX represent fundamentally different terminal performance philosophies rather than marginally different products. Added FAQ covering six common questions, including direct treatment of the weight-retention correction. Applied full internal linking throughout.
