Introduction
Lapua’s FMJ (Full Metal Jacket) bullet line is a product category fundamentally different from every other bullet covered in this site’s series. While the preceding articles addressed varmint, hunting, and match bullets designed to either expand, fragment, or maintain precise BC for competition, the FMJ is designed for none of those outcomes. A full metal jacket bullet has a lead core completely enclosed in a metal jacket, leaving no exposed lead at the tip or base (in the case of a full metal jacket boat-tail, the base is enclosed). On impact, an FMJ does not expand, does not fragment reliably, and does not produce the terminal performance characteristics that make a hunting bullet ethically appropriate for game harvest.
This makes the FMJ appropriate for a different and specific set of applications: training at volume, service rifle competition where FMJ is required by the rules, plinking and general target practice, and bore-safe ammunition for jurisdictions where lead-exposed bullets are prohibited from public ranges. At Lapua’s quality level, the FMJ also serves as a precision practice bullet for shooters who want match-quality consistency in their training ammunition at a lower per-bullet cost than premium hollow-point match bullets.
Lapua’s FMJ specifically uses a tombac jacket – a copper-zinc alloy rather than pure copper or the harder gilding metal used in some other manufacturers’ bullets. Tombac is softer and more easily formed than some alternatives, enabling Lapua’s tight manufacturing tolerances, and produces a somewhat distinctive golden color compared to the brighter appearance of higher-zinc gilding metal jackets. This is the same tombac construction Lapua uses across its entire bullet lineup, distinguishing Lapua products from competitors regardless of bullet type.
The market position of the Lapua FMJ is worth understanding before examining the specifications. This is not a budget training bullet in the way that bulk military surplus or generic commercial FMJ products are budget training bullets. It is the premium tier of the FMJ training bullet market, priced at $0.30-$0.60 per bullet – comparable to or slightly above the pricing of some entry-level match hollow-points. The value proposition is Lapua’s manufacturing consistency at this price tier: tighter weight uniformity, better concentricity, and more consistent BC from bullet to bullet than bulk FMJ, producing lower ES and SD figures in handloaded training ammunition. Shooters who are serious about their training want their practice ammunition to perform consistently even when it is not their best match-grade hollow-point, and the Lapua FMJ delivers that consistency within the FMJ category.
For trajectory context on the cartridges most commonly paired with this bullet, see the 223 Remington ballistics guide, 6.5 Creedmoor ballistics guide, and 338 Lapua Magnum ballistics guide.
Two competitor BC figures in the original article require correction. The MatchKing BC range is cited as 0.300-0.600, while this site’s dedicated MatchKing coverage documents 0.400-0.700 – the lower bound is significantly understated. The Berger Hybrid Target BC range is cited as 0.400-0.700, while this site’s documentation shows 0.524-0.841 – again, the upper end is substantially understated. Both follow the same pattern this series has documented repeatedly.
The original article’s stated BC range of “0.172 to 0.450” for the Lapua FMJ is internally inconsistent with the ballistics table, which shows no entry with BC 0.172. The table minimum is 0.250 for the 55-grain .224-inch entry. This may reflect an entry in the original source data that was not included in the published table, or it may be a data transcription error. For trajectory calculation purposes, use the table values and verify at lapua.com.
Disclaimer: Reloading is an inherently dangerous activity. Always consult current published load data from Lapua or other reputable sources before loading any cartridge. Start at the published minimum charge and work up carefully while watching for pressure signs. Never exceed maximum published loads. The information on this page is for educational reference only and does not replace a current reloading manual.
Important application note: The Lapua FMJ is a full metal jacket bullet designed for target shooting, training, and competition practice – not for hunting. FMJ bullets do not expand reliably on game tissue and are not appropriate for hunting applications in most jurisdictions. For hunting use, see the dedicated hunting bullet articles elsewhere on this site.
Technical Characteristics
Tombac jacket, lead core: The Lapua FMJ uses a tombac (copper-zinc alloy) jacket over a swaged lead core, with the jacket extending to completely cover the bullet tip. This construction is optimized for feeding reliability, dimensional consistency, and barrel-friendliness rather than terminal expansion. The tombac jacket’s composition and formation is Lapua’s standard across its product line.
The tombac choice is worth contrasting with alternatives. Most American FMJ bullets use gilding metal (95/5 copper-zinc or similar), while some economy FMJ products use mild steel jackets with copper plating. Tombac sits between these in hardness and is notably well-suited to the precise swaging processes Lapua uses for its premium products. The practical result is that Lapua FMJ bullets are exceptionally uniform in jacket thickness and concentricity – a property that matters more at 300+ yards than at indoor pistol ranges, and which is a primary reason serious rifle shooters choose Lapua FMJ over bulk alternatives when cost allows.
Full Metal Jacket – no expansion: This is the defining characteristic of the FMJ category. Unlike all other bullets in this site’s series – whether bonded hunting bullets, monolithic copper expanding bullets, or hollow-point match bullets – the FMJ is specifically designed not to expand. The enclosed tip and thick jacket suppress deformation on impact. This means the FMJ passes through soft target media without mushrooming, which is appropriate for paper targets, steel plates, and training scenarios but not appropriate for ethical game harvest.
Boat-tail options: The original article notes that many Lapua FMJ variants are available in boat-tail configurations, which reduces base drag and improves BC compared to flat-base equivalents. The specific weights available in boat-tail versus flat-base configurations should be verified at lapua.com. The 185-grain .308 and 250-grain .338 entries in the table are likely boat-tail given their relatively high BCs for FMJ bullets at those weights.
Tombac’s manufacturing advantage: The specific alloy composition that Lapua uses in its tombac jacket is proprietary to the company. What is documented and consistent across multiple sources is that Lapua’s dimensional tolerances for its FMJ bullets are tighter than typical commercial FMJ production, producing better weight uniformity and jacket concentricity than bulk-grade FMJ alternatives. The original article’s claim of 10-15% less fouling than “standard FMJ bullets” is directionally plausible given Lapua’s tighter tolerances and the tombac composition, though the specific percentage is not independently verifiable.
Not lead-free: The Lapua FMJ contains a lead core and is not legal for hunting in California’s condor zones or other lead-restricted hunting areas. For range shooting where lead projectiles are permitted, the FMJ is fully appropriate.
Ballistics and Performance
G1 BCs from 0.250 to 0.450 per the table span the Lapua FMJ lineup. These are lower than the premium match hollow-point bullets this site has covered – the MatchKing reaches 0.700, the Hybrid Target reaches 0.841 – which is expected given that FMJ construction does not optimize for the aerodynamic efficiency that hollow-point and boat-tail match designs achieve at comparable weights.
The 55-grain .224-inch at BC 0.250 and SD 0.157 covers 223 Remington for training and plinking. At BC 0.250, this is at the lower end of the FMJ performance envelope for .224-inch bullets, but appropriate for the close-range and mid-range training applications where 55-grain .223 Remington loads are most commonly used. The 55-grain FMJ is the most common training bullet weight for AR-15 platforms and is the weight most associated with volume-practice ammunition. At a 1:9 or faster twist, 55-grain FMJ bullets stabilize reliably; the heavier 69-grain variant requires 1:9 or faster and is not appropriate in 1:12 twist barrels still found in some older AR-15 rifles.
The 69-grain .224-inch at BC 0.310 and SD 0.196 covers 223 Remington for service rifle competition and longer-range training at .224-inch caliber. The BC 0.310 is meaningfully better than the 55-grain entry (0.250), and at 300 yards this difference translates to approximately 1-2 inches less drop and slightly better wind resistance – meaningful for service rifle competition even in the FMJ category. This weight requires a 1:9 or faster twist to stabilize reliably.
The 100-grain .264-inch (6.5mm) at BC 0.300 and SD 0.205 covers 6.5 Creedmoor and 6.5×55 Swedish Mauser for training use. The BC 0.300 is moderate for this weight class.
The 144-grain .264-inch at BC 0.350 and SD 0.295 is a service rifle competition and military training weight, historically associated with FMJ bullets in Scandinavian military service (the 6.5x55mm was the Swedish and Norwegian standard service cartridge for decades). Lapua’s production heritage in military bullet manufacture is directly relevant here – the company was founded as a Finnish state-owned military ammunition manufacturer and has been producing precision 6.5mm FMJ bullets for service use since the mid-20th century. The 144-grain 6.5mm FMJ represents the most historically significant entry in this table from that production heritage perspective, connecting the Lapua FMJ line to its military origins.
The 123-grain .308-inch at BC 0.310 and SD 0.185 is a lighter FMJ weight for .308-inch training. While 123 grains is light for the .308-inch bore (most .30 caliber bullets for 308 Winchester start at 150 grains), this weight is sometimes used for reduced-recoil training loads. Verify this weight’s stabilization requirement – most 308 Winchester barrels with 1:10-1:12 twist may not stabilize 123-grain FMJs reliably.
The 144-grain and 185-grain .308-inch at BC 0.370 and 0.450 cover 308 Winchester for mid-range training and service rifle competition. The 185-grain at BC 0.450 is the strongest BC in the .308-inch FMJ category this table shows, and at this BC approaches the lower range of some entry-level match hollow-point bullets. For service rifle competitors who train at 300-600 yards with 308 Winchester, the 185-grain Lapua FMJ represents a practical choice that delivers consistent performance at a lower per-round cost than equivalent match hollow-points, while still providing meaningful BC relative to lighter FMJ alternatives at this caliber.
The 200-grain and 250-grain .338-inch at BC 0.420 and 0.450 cover 338 Lapua Magnum for training use with this extreme-range military cartridge. At $0.30-$0.60 per bullet versus $1.50-$2.50+ for premium .338 Lapua match bullets, FMJ training loads represent a substantial cost reduction per round. For a shooter running 200 rounds of training drills at moderate range (300-600 yards), this difference is $100-$400 per session – a meaningful figure that affects how much trigger time a serious 338 Lapua shooter can accumulate before a match. The BC 0.450 for the 250-grain is competitive within the FMJ category, though it trails the Lapua Scenar-L at significantly higher BC in the same caliber and weight.

Comparison Bullets
The original article’s comparison set – Sierra MatchKing and Berger Hybrid Target – is an unusual pairing for an FMJ article, as those bullets are premium precision match bullets designed for very different applications. A more useful comparison for a training FMJ would be against other FMJ bullets at the same price tier. The MatchKing and Hybrid Target comparison does highlight the BC disadvantage of the FMJ relative to premium match bullets, which is the relevant performance context for a shooter deciding whether to use FMJ training loads versus match hollow-points.
The BC figures for both competitors require the same corrections documented throughout this series. The MatchKing (0.300-0.600 in the original versus this site’s documented 0.400-0.700) and Hybrid Target (0.400-0.700 in the original versus this site’s documented 0.524-0.841) are both understated, and the corrected figures show the FMJ trailing these premium designs by an even larger margin than the original article suggests.
The Lapua Scenar and Lapua Scenar-L are the relevant within-brand upgrades from the FMJ for precision target shooting. The Lapua Mega and Lapua TRX are Lapua hunting bullets for comparison context. The Lapua MaxRange is an additional Lapua target bullet covering extended range applications. Both use hollow-point boat-tail construction for significantly better BC than the FMJ at comparable weights, making them appropriate when group precision rather than volume-training cost is the priority.
The Lapua Lock-Base is a further Lapua product in the tactical/military design space, with a patented locked base and higher BCs than the standard FMJ for .308 and .338 applications. The Lapua Naturalis is Lapua’s lead-free hunting option for shooters who want consistent manufacturer components across both their training (FMJ) and hunting (Naturalis) loads.
Comparison Table – Target and Training Bullets
| Bullet | BC Range | Jacket Type | Expansion | Application |

Applications and Practical Aspects
Training and volume shooting (.224-inch, 55-69 grains): 223 Remington for volume AR-platform training and general target practice. Hodgdon Varget, Hodgdon CFE 223, Hodgdon Benchmark, and Accurate 2230 are standard powder choices for the 55-grain weight. Alliant Reloder 15 is a further documented option for the heavier 69-grain weight.
6.5mm service rifle and military training (.264-inch, 100-144 grains): 6.5 Creedmoor and 6.5×55 Swedish Mauser for training. Hodgdon H4350 and Alliant Reloder 16 are standard choices.
308 Winchester training and competition (.308-inch, 144-185 grains): 308 Winchester for service rifle competition training. Hodgdon Varget, Hodgdon H4895, IMR 4064, and IMR 4895 are standard training load choices. The 308 Winchester ballistics guide provides trajectory reference for training load planning.
338 Lapua Magnum training (.338-inch, 200-250 grains): 338 Lapua Magnum for training with this extreme-range military and long-range sporting cartridge at reduced cost versus premium match bullets. Alliant Reloder 33, Hodgdon H1000, Hodgdon Retumbo, Hodgdon H4831SC, and Alliant Reloder 22 are standard powder choices.
Reloading
Primers: CCI 400, Federal 205, and Remington 7½ standard small rifle primers for .224-inch. CCI 200 and Federal 210 large rifle for .264-inch and .308-inch; CCI BR-4 benchrest primer for consistency-sensitive .264/.308 training loads. Federal 215 magnum primers for 338 Lapua Magnum. For AR-platform semi-automatic .223/.308 use, CCI No. 41 and CCI No. 34 are appropriate for slam-fire prevention.
Cases: Lapua’s own brass is the natural pairing for Lapua bullets, particularly in 308 Winchester and 338 Lapua Magnum where Lapua brass is among the most respected premium sources available. Standard commercial brass from Winchester or Remington is appropriate for .223 Remington training loads.
Crimp: Light roll crimp into the cannelure for semi-automatic platforms where bullet setback from feeding force could be an issue.
Seating depth: 0.010-0.050 inches off the lands per the original article. The FMJ’s tombac jacket and full metal construction means it is somewhat less sensitive to seating depth than precision match hollow-points, but consistent seating still improves ES/SD in training loads.

Frequently Asked Questions
Q: Can the Lapua FMJ be used for hunting?
A: No, and this must be stated clearly. FMJ bullets do not expand reliably on game tissue and would produce inadequate wound channels for ethical, reliable game harvest. The tombac jacket is specifically designed not to peel back on impact – the properties that make it excellent for target and training use (consistent shape retention, reliable feeding, minimal deformation) are exactly the properties that make it unsuitable for hunting. Using FMJ bullets for hunting is illegal in many jurisdictions and is ethically inappropriate regardless of legality. In North America, regulations in most states and provinces require expanding bullets for hunting big game; in Europe, many countries have moved to explicitly prohibiting FMJ for hunting. For hunting, use a dedicated expanding hunting bullet appropriate for the caliber and game – this site’s hunting bullet articles cover the available premium and economy options across all relevant calibers.
Q: How does the Lapua FMJ compare to match hollow-point bullets for precision shooting?
A: The comparison is one-dimensional – BC. Match hollow-points (MatchKing, Hybrid Target, LRHT) achieve significantly higher BCs than FMJ bullets at comparable weights, producing flatter trajectories and less wind drift at range. At 100-200 yards, the BC difference is less practically significant; at 300-500 yards, match hollow-points’ trajectory and wind resistance advantage becomes meaningful for precision shooting. For training at typical service rifle distances (100-300 yards), the FMJ’s lower cost may outweigh its BC disadvantage. For precision competition at 600-1,000+ yards, a match hollow-point is the correct choice.
Q: The original article cites the MatchKing BC range as 0.300-0.600. Is this accurate?
A: No. This site’s dedicated MatchKing coverage documents 0.400-0.700 per Sierra’s primary source data. The lower bound (0.300) is substantially understated. Similarly, the Hybrid Target BC (0.400-0.700 in the original) is understated relative to this site’s documentation (0.524-0.841). These follow the same pattern documented throughout this series.
Q: What is tombac and how does it differ from other jacket materials?
A: Tombac is a copper-zinc alloy with higher zinc content than the gilding metal (95/5 copper-zinc) used in many American FMJ bullets. Lapua does not publicly specify the exact composition of its tombac alloy, but the resulting material is somewhat softer than gilding metal and produces a slightly different color (more golden-yellow versus bright copper). Lapua specifically uses tombac across its entire bullet lineup – the FMJ, Scenar, Scenar-L, and Naturalis all use tombac jacketing. The material choice is consistent with Lapua’s Scandinavian production heritage and is suited to Lapua’s precision forming processes.
Q: Why would a handloader use Lapua FMJs instead of cheaper bulk FMJ bullets?
A: Manufacturing consistency. Lapua FMJ bullets are produced to tighter dimensional and weight tolerances than bulk FMJ bullets from commercial sources, producing lower ES and SD in handloaded ammunition and potentially tighter groups than equivalent bulk FMJ. For a shooter training seriously at quality facilities who wants the cost savings of FMJ versus premium match bullets but still wants ammunition that performs consistently, Lapua FMJ represents the premium tier of the FMJ market.
Q: For 338 Lapua Magnum training, how much cost savings does the FMJ offer versus match bullets like the Scenar?
A: Substantial. At the original article’s cited $0.30-$0.60 per FMJ bullet versus $1.00-$2.00+ per premium 338 Lapua Magnum match bullet, a 500-round training session represents $200-$750 in FMJ costs versus $500-$1,000+ for match bullets. The BC and precision difference is real but less consequential for close-range training (200-400 yards) than for match competition at 1,000+ yards.
Conclusion
The Lapua FMJ occupies a distinct position in this site’s bullet coverage as the only full metal jacket bullet in the series – a training and service rifle bullet designed specifically not to expand, optimized for consistent flight and reliable feeding rather than terminal performance. Lapua’s tombac jacket and precision manufacturing bring match-grade consistency to the FMJ category, distinguishing it from bulk commercial FMJ alternatives at a modest price premium.
The data quality observation from this article: the MatchKing BC comparison (0.300-0.600 versus this site’s documented 0.400-0.700) and the Hybrid Target comparison (0.400-0.700 versus documented 0.524-0.841) both follow the exact same understatement pattern documented throughout this series. The lower bound for the MatchKing and the upper bound for the Hybrid Target are consistently wrong in the same direction across a dozen or more articles now, suggesting the errors originate from the same secondary source rather than from independent research in each article. For training load planning where BC matters less than at match distances, these comparison inaccuracies are less consequential than they would be for a precision hunting or competition article – but they are noted for consistency.
Choose the Lapua FMJ if: you need volume training ammunition with consistent performance at a lower cost than premium match hollow-points; you shoot service rifle competition formats where FMJ is required by class rules; or you train with 338 Lapua Magnum and want to reduce per-round cost for close-range training sessions.
Choose something else if: you need expansion for hunting – no FMJ is appropriate for hunting, period. If you are shooting precision competition beyond 300 yards, upgrade to the Lapua Scenar, Sierra MatchKing, or Berger Hybrid Target for meaningfully better BC and accuracy potential.
Disclaimer: FMJ bullets are not appropriate for hunting. Reloading involves inherent risks; always use current load data from Lapua or other published manuals. For AR-platform semi-automatic use, use mil-spec primers (CCI No. 41 for small rifle, CCI No. 34 for large rifle) to prevent slam-fire incidents. Wear eye protection at all times.
