.22 Creedmoor INFO and LOAD DATA from Peterson Cartridge

Peterson Cartridge Company (“Peterson”) has released a lengthy, authoritative guide to the 22 Creedmoor cartridge, a popular wildcat based on the 6.5 Creedmoor or 6mm Creedmoor necked down to .224 caliber. We think the .22 Creedmoor would be a great long-range varmint cartridge, similar to the .22-250 Rem, but with a more modern, efficient cartridge design. In addition, some PRS/NRL competitors may turn to the .22 Creedmoor because it has less recoil and is flatter-shooting than the 6mm Creedmoor. In addition, .224-caliber match bullets are typically less expensive than heavier 6mm and 6.5mm projectiles. Less recoil, and less cost — what’s not to like?*

Along with load data, this article has specific sections dedicated to: Primers, Rifling Twist Rates, and Reloading Supplies. If you are considering building a .22 Creedmoor, we recommend you download the full Peterson .22 Creedmoor article, which is available in PDF format.

Peterson states, “Since its inception in 2007… the 6.5 Creedmoor has seen some pretty meteoric growth in popularity. That growth continues as of this writing, as the cartridge has now gone mainstream with hunters and shooters alike. As the popularity of the 6.5 Creedmoor has increased, so has the number of wildcat cartridges based off of it. Some of those popular wildcat cartridges are the 6mm Creedmoor, the .25 Creedmoor, and now the .22 Creedmoor. This data sheet will cover the .22 Creedmoor.

To help our customers, and anyone else who shoots .22 Creedmoor, we decided to create this Data Sheet and distribute it. [In this LOAD DATA Document] you will find four (4) common bullets, and four (4) common rifle powders used when handloading the .22 Creedmoor cartridge. We then took the different bullet and powder combinations and loaded them up to the SAAMI Maximum Average Pressure (MAP) for the 6.5 Creedmoor and 6mm Creedmoor cartridges, which is 62,000 PSI. [O]ur goal was to provide a wide spectrum of bullet weights and the powders used with them.

All of the following data was gathered by our ballistician in our indoor ballistics lab located in our factory in Pennsylvania. Although we were able to gather pressure and velocity data in our lab, we have NOT tested these loads for accuracy. Again, these loads are just designed to give shooters information regarding what velocity, a given bullet and powder charge combination, will produce the SAAMI Maximum Average Pressure (MAP) of 62,000 psi.”

IMPORTANT — Pressures can vary significantly with different Cartridge Overall Lengths (COAL). In addition, ANY change to ANY load components — primers, bullets, brass, powder — can affect pressure. Always load conservatively. In addition, because of variances in bore dimensions, some barrels may show higher pressures than others. Again, always start with conservative loads, well below MAX pressures.

*Actually there IS a potential downside — reduced barrel life. We expect that a .22 Creedmoor running hot varmint loads would experience shorter useful barrel life compared to a 6.5 Creedmoor. This is based on what we’ve observed with .22-250 and .22-250 Ackley barrels compared to our 6.5 CM barrels.
