Remington Centerfire Primer for 9-1/2 Magnum Rifle - X22622

Remington 9 1/2M Large Rifle Magnum Primers are engineered for shooters who demand unfailing ignition in extreme environments. Each Remington 9 1/2 M primers is rigorously tested from –20 °F to +150 °F, guaranteeing dependable spark whether you are glassing mule deer in sub-zero winds or hammering steel in blistering summer matches. The hotter flame front reliably lights slow burning magnum powders, stabilising velocities in big-bore cartridges like .300 Win Mag, .338 Lapua, and hard?hitting .375 Ruger.

Precision Machined Cups Resist High Pressure Flow

Remington controls primer cup dimensions to four decimal places, keeping wall thickness uniform for flawless seating and a secure pressure seal. This meticulous machining prevents cratering and gas leakage under pressures that routinely exceed 60 000 psi in modern magnum rifles. The thicker, work hardened brass also extends bolt face life, making these large rifle magnum primers ideal for both hunting rifles with tight firing pin channels and custom bench rest actions running hot loads.

• Hot magnum flame reliably ignites slow burn powders for big bore and long range cartridges
• Primer cup dimensions held to 0.0001" for perfect seating and high pressure integrity
• Tripod anvil design enlarges strike area, cutting misfires in cold or fouled actions
• Tested for dependable spark across –20 °F to +150 °F operating range
• Pellet weight controlled to 0.01 g, tightening SD/ES for match grade accuracy

Inside every 9 1/2M Magnum Primers sits Remington’s signature tripod anvil—a three leg design offering a larger, more forgiving strike surface. This geometry converts even marginal firing pin blows into sure ignition, a crucial edge when frosty lubricants, fouling, or lightened competition springs threaten reliability. The resulting instant flame cuts lock time variance and keeps extreme spreads tight for predictably flat trajectories at distance.

The specially formulated priming mix resists degradation from ambient humidity swings, so unopened bricks remain within spec for years when stored in a cool, dry safe. Hunters who stock ahead of tag draws and match competitors who batch load by lot number alike appreciate the confidence of chemistry proven by decades of Remington QA data.
