Starline and Alpha Munitions also now offer 6.5 Creedmoor brass formed with Small Rifle primer pockets.

Advantages of using a Small Rifle primer rather than the typical Large Rifle version are twofold. Use of the smaller, less aggressive cap can result in better consistency, particularly in the form of tighter standard deviations.

While this matters little inside common hunting distances, it’s a big deal to shooters reaching past a half-mile, where a mere 20-fps difference between shots can equate to inches of vertical impact difference on the target. beacsue

Additionally, a small primer pocket leaves more material intact than a large primer pocket. The case head is left stronger and less susceptible to pressure-caused deformation. Handloaders searching for the last iota of long-range performance can push bullets faster—using aggressive charges on the cusp of safe pressure limits—without loosening primer pockets.

As a result, savvy competitors with long-barreled match rifles can . achieve muzzle velocities a solid 100 to 200 fps faster than typical factory-ammo speeds with a given bullet. Only experienced handloaders should attempt this. Always start low, work up slowly and carefully until you see early pressure signs, and then back off a bit. and also

 

Master riflesmith and PRS shooter Clayton Smith has pioneered a unique 7mm wildcat,.

the 7mm SAW, that showcases the advantages of the Small Rifle primer pocket. Formed from Lapua’s .308 Win. small-pocket Palma brass, it features an “improved”

profile with a sharp shoulder angle and little body taper. Because the Small Rifle primers pocket enables the case head to maintain integrity while operating at chamber pressures in the upper spectrum,

the little hotrod pushes 7mm bullets to unprecedented speeds for a short-action, standard-diameter cartridge.

The advantages of Small Rifle primer pockets in standard-size centerfire cartridges don’t come free. In an issue of RifleShooter’s sister magazine Shooting Times, handloading editor Lane

Pearce addressed potential pressure issues related to the use

of small pockets in standard-size cases, and he went so far as to advance some stark advice against using them except in specific circumstances. If you can hunt up a back issue, it’s worth a read.

When temperatures plummet, propellants become increasingly difficult to ignite evenly, particularly those made of a double-base compound containing nitroglycerine. There goes the added consistency you gained by using a Small Rifle primer. Stubborn ignition could theoretically go so far as to cause a slight hangfire in extreme cold.

For hunters,

however, opting to use standard-size rifle cases perforated with Small Rifle primer pockets is usually a poor decision, unless they live in mild climates and rarely hunt in temperatures below freezing. Using standard Large Rifle primers ensures reliable ignition in just about any temperature.
