.22 Creedmoor Ammo
The .22 Creedmoor is the long-range .22 caliber cartridge that pushes the 6.5 Creedmoor case to .224 caliber bullets at extreme velocity — producing one of the flattest-shooting, hardest-hitting varmint and predator cartridges ever developed. Originally a wildcat cartridge, .22 Creedmoor became a SAAMI-standardized round in 2024 and now appears in factory ammunition from Hornady, Federal, and other major manufacturers. Impact Guns carries .22 Creedmoor ammunition.

From Wildcat to Production
The .22 Creedmoor began as a wildcat necking the 6.5 Creedmoor case down to .224 caliber. Shooters experimenting with the design found exceptional long-range performance — flat trajectory, modest recoil, and ballistic performance approaching .22-250 with longer barrel life. SAAMI standardization in 2024 brought factory ammunition and rifles into the market, and the cartridge has gained rapid following among varmint hunters, predator hunters, and long-range precision shooters who want .224-caliber performance beyond what the .22-250 or .223 Remington can provide.
What .22 Creedmoor Is Built For
Long-range varmint and predator hunting is the cartridge’s sweet spot — prairie dogs at 600+ yards, coyotes at 500+ yards, bobcats and other predators at extended distances where standard varmint cartridges run out of energy. Long-range precision shooting and competition at .224 caliber level is the secondary application. The cartridge isn’t intended for big game; bullet weight tops out at 90 grains, which is below most ethical big-game thresholds.
Compared to .22-250 and .224 Valkyrie
.22 Creedmoor delivers comparable or slightly better velocity than .22-250 with longer barrel life and modern case geometry. .224 Valkyrie was designed for AR-15 platform compatibility and is shorter than .22 Creedmoor; the Valkyrie fits an AR-15 lower, the Creedmoor requires bolt-action or AR-10 platforms. For absolute long-range performance in a bolt gun, .22 Creedmoor leads both alternatives.
Rifle Requirements
The .22 Creedmoor requires bolt-action or AR-10 platform rifles with appropriate magazine length and twist rates of 1:7 or 1:8 to stabilize modern heavy .224 bullets. Bergara, Christensen Arms, Sako, Howa, and Tikka offer .22 Creedmoor chambering. 26-inch barrels are standard for maximum velocity; 24-inch reduces velocity 100–150 fps without dramatic performance loss.
Frequently Asked Questions: .22 Creedmoor
Is .22 Creedmoor better than .22-250?
For long-range varmint shooting, generally yes — comparable or slightly higher velocity, longer barrel life, better case geometry for modern bullets, and good factory ammunition availability. For traditional varmint shooting under 400 yards, .22-250 remains an excellent cartridge with broader ammunition history.
Can .22 Creedmoor be used for deer?
Bullet weights cap around 90 grains, which is below most state ethical minimums for deer hunting. The cartridge is intended for varmint and predator use, not big game. Verify your state’s regulations before using any .224-caliber cartridge for deer.
What barrel twist do I need for .22 Creedmoor?
1:7 or 1:8 twist is required to stabilize the heavy 80–90 grain .224 bullets that take full advantage of the cartridge’s long-range potential. Older 1:9 or 1:10 twist barrels won’t stabilize the heavier bullets and limit the rifle’s effective range significantly.
