Accurate 2495

Discover the secrets of Accurate 2495, the reliable propellant for medium-capacity rifle cartridges. Unlock precision reloading for exceptional performance.

The world of precision reloading often revolves around finding the perfect balance between versatility and consistency. For decades, Accurate 2495 has stood as a cornerstone propellant for those seeking a reliable, high-performance solution for medium-capacity rifle cartridges. Originally designed to mimic the legendary performance of IMR 4895, Accurate 2495 has carved out its own reputation as a “workhorse” powder that excels in everything from classic military surplus rifles to modern target platforms.

Whether you are loading for the venerable 30-06 Springfield used in the M1 Garand or developing a precision load for a 308 Winchester bolt gun, Accurate 2495 provides the consistent pressure curves and excellent ignition required for sub-MOA results. This guide will dive deep into the technical nuances, comparative performance, and optimal component pairings for this exceptional propellant.

Powder Description & Technical Profile

Accurate 2495 is a single-base, extruded (stick) propellant. It is characterized by its “short-cut” grain geometry, which was specifically engineered to address the historical metering issues associated with longer-grained stick powders. Unlike traditional extruded powders that can “bridge” in powder measures, the shortened kernels of Accurate 2495 flow with a level of consistency that approaches some spherical powders, while maintaining the thermal stability inherent to the extruded manufacturing process.

The Expert “Feel”

Reloaders often describe the performance of Accurate 2495 as having a “progressive push.” In gas-operated rifles like the M14 or M1 Garand, this is critical. The powder provides sufficient port pressure to cycle the action reliably without creating the sharp, violent pressure spikes that can damage vintage operating rods. In bolt-action rifles, this translates to a predictable recoil impulse and a wide accuracy node, making it forgiving during the load development process.

Pros & Cons

  • Pros:
    • Optimized port pressure for semi-auto actions.
    • Short-cut grains for improved volumetric metering.
    • Excellent ignition with standard large rifle primers.
    • Clean-burning properties with minimal carbon fouling.
  • Cons:
    • Not as temperature-insensitive as some “Extreme” line competitors.
    • Slightly lower top-end velocities in magnum cases compared to slower propellants.

Technical Characteristics

The physical and chemical makeup of Accurate 2495 determines its behavior inside the brass and during the ignition cycle. Below is the technical breakdown of its properties.

Temperature Stability & Burn Rate Analysis

While Accurate 2495 is a single-base powder – which generally offers better stability than double-base spherical powders – it is not marketed as a “temperature-insensitive” powder in the same vein as the Hodgdon Extreme series. Reloaders can expect a moderate shift in muzzle velocity as ambient temperatures move from freezing to peak summer heat.

On average, Accurate 2495 exhibits a velocity variance of approximately 0.5-0.8 FPS per degree Fahrenheit. For the average hunter or local match shooter, this is negligible. However, for extreme long-range competitors, it is advisable to develop a “summer” and “winter” load or to keep ammunition in an insulated container to maintain a consistent point of impact.

Powder Comparison

To understand where Accurate 2495 fits in the market, we must compare it to its most frequent competitors. It occupies a crowded space, often being swapped for other mid-range rifle powders when availability fluctuates.

  1. IMR 4895: The closest relative. Accurate 2495 was built to follow this data, though it typically requires 1-2% more weight to achieve identical velocities.
  2. Hodgdon H4895: A slightly more temperature-stable version of the 4895 formula. It is often considered the gold standard for the “4895 class” but is frequently harder to find than the Accurate version.
  3. Alliant Reloder 15: Slightly slower in burn rate. It often produces higher top-end velocities in 308 Winchester but lacks the specific pressure curve benefits for older semi-autos that Accurate 2495 provides.
  4. Accurate 2520: Often called the “Camp Perry Powder,” this is the spherical sibling to Accurate 2495. It meters perfectly but is more temperature-sensitive and has a different pressure profile.

Performance, Metering & Equipment

Metering Consistency

Because Accurate 2495 uses a “short-cut” grain design, it is much easier to meter through volumetric measures than traditional long-grain stick powders like IMR 4064. On a high-quality measure such as the RCBS Uniflow Powder Measure 3, you can expect charges to stay within +/- 0.1-0.2 grains. For those chasing absolute precision, using a RCBS MatchMaster Digital Powder Scale & Dispenser or a Frankford Arsenal Powder Trickler will allow for kernel-by-kernel consistency.

Fouling and Cleanliness

Accurate 2495 is treated with modern flash suppressants, making it an excellent choice for tactical or low-light applications. Carbon fouling is minimal, especially when used at the upper end of its pressure range. Like most single-base powders, it burns most efficiently when it reaches its “ideal” pressure (typically 45,000-55,000 PSI). Using it for reduced loads may result in slightly more “sooty” cases, but it rarely produces the heavy copper-carbon “crust” associated with some older double-base propellants.


The versatility of Accurate 2495 allows it to span from small-bore varmint rounds to classic military bolt actions. Below are the primary recommendations.

Primers

Consistent ignition is the heartbeat of accuracy. Accurate 2495 is easy to ignite and does not typically require magnum primers unless you are loading in extremely cold sub-zero conditions.

  1. CCI 200: The standard large rifle primer used in most load development for this powder.
  2. Federal 210: Known for extreme sensitivity and consistent “soft” cups.
  3. Winchester WLR: Provides a very hot flame, excellent for ensuring complete combustion.
  4. Remington 9-1-2: A reliable all-around performer for hunting applications.
  5. RWS 5341: A premium European option for those seeking the ultimate in shot-to-shot consistency.
  6. Fiocchi Large Rifle: An excellent high-volume option that performs very similarly to the CCI 200.
  7. Sellier-Bellot V360587: Provides very consistent primer pocket fitment and ignition.
  8. CCI 34: The “Military” primer. Essential for 308 Winchester and 30-06 Springfield loads in semi-autos to prevent slam-fires.
  9. Federal GM210M: Gold Medal Match primer for precision long-range work.

Conclusion

Accurate 2495 remains one of the most underrated powders in the Western Powders lineup. While many reloaders gravitate toward the “name brand” recognition of the 4895 series, Accurate 2495 offers nearly identical performance with arguably better metering and availability. Its ability to serve as a single solution for the most popular cartridges in the world – 223 Remington, 308 Winchester, and 30-06 Springfield – makes it an essential component on any reloader’s shelf.

If you are a high-volume shooter or a vintage rifle enthusiast, this powder is a technical masterpiece that respects the history of firearms while utilizing modern chemical advances to provide a cleaner, more consistent shooting experience.

Expert Pro Tip: When loading Accurate 2495 for the M1 Garand, aim for a muzzle velocity of approximately 2700-2750 FPS with a 150 grain bullet. This replicates the M2 Ball specification perfectly. To ensure the longest life for your rifle’s operating rod, use the CCI 34 military primer and a moderate crimp to prevent bullet setback during the semi-auto feeding cycle.
