Peterson Cartridge Company (“Peterson”) has published a comprehensive guide to the 22 Creedmoor cartridge. This popular wildcat is based on either the 6.5 Creedmoor, or the 6mm Creedmoor, and lowered down to.224 caliber. The.22 Creedmoor is a long-range varmint cartridge that we believe would be comparable to the.22-25 Rem but with a more modern and efficient cartridge design. The.22 Creedmoor may be preferred by PRS/NRL competitors because it has a flatter-shooting design and less recoil than the 6mm Creedmoor. Match bullets of.224 caliber are usually less expensive than heavier 6mm or 6.5mm projectiles. What’s not to love? *

Peterson stated, “Since its creation in 2007, the 6.5 Creedmoor’s popularity has seen a meteoric rise.” The cartridge is now a mainstream choice for hunters and shooters. The number of wildcat cartridges that are based on the 6.5 Creedmoor have increased as a result. The.25 Creedmoor is also a popular wildcat cartridge, as well as the 6mm Creedmoor and the.22 Creedmoor. This data sheet will include the.22 Creedmoor.
This Data Sheet was created to assist our customers and anyone who shoots.22 Creedmoor. This LOAD DATA document contains four (4) common bullets and four (4) common rifle powders that are used for handloading the.22 Creedmoor. The bullet and powder combinations were then loaded up to the SAAMI Maximum Pressure (MAP), which is 62,000 PSI for the 6.5 Creedmoor or 6mm Creedmoor cartridges. Our goal was to offer a wide range of bullet weights as well as the powders that were used with them.
All of the data below was collected by our ballisttician in our indoor ballistics laboratory located in our factory, Pennsylvania. These loads were not tested for accuracy, although we were able gather velocity and pressure data in our lab. These loads are only intended to provide information to shooters about the SAAMI Maximum Average Pressure, (MAP), of a given bullet and powder combination.
Sample 22 Creedmoor LOAD DATA
Important: Pressures can vary greatly depending on the length of the Cartridge Overall Length (COAL). Any modification to any load component — primers bullets brass, powder — can impact pressure. Always load with caution. Due to differences in bore dimensions, barrels may have higher pressures than others. Always start with conservative loads that are well below MAX pressures.
*There is a potential downside to this — a shorter barrel life. A.22 Creedmoor that is subject to hot varmint loads will have a shorter useful barrel lifespan than a 6.5 Creedmoor. This is based upon what we have observed with.22-252 and.22-252 Ackley barrels compared with our 6.5 CM barrels.
