Companies are coming out with better and better .25 calibre bullets. And of course, good bullets paired with good casings equals good results at the target.

Because much of the market for this calibre is long-distance competition shooters Peterson designed these casings with Small Rifle Primer pockets.

Peterson casings are known for really consistent internal volume from case to case. This results in single digit muzzle-velocity standard deviations. Peterson is also known for extremely consistent neck tension, which results in uniform bullet release from shot to shot, and casing hardness values that result in an uncommonly high number of reloads.

Peterson's .25 Creedmoor includes all of those features. But when they designed the tool pack to make the .25 Creedmoor, they went one step further and created the ideal neck wall thickness. As you might imagine, when a handloader necks down a larger caliber it can result in a neck wall that is a bit too thick. Necking up a smaller caliber can result in a neck wall that is a bit to thin. Peterson's .25 Creedmoor has been designed from scratch, with the ideal neck wall thickness.

If you think the .25 Creedmoor is an up-and-coming calibre, and you want to shoot correctly headstamped casings, try Peterson Brass.

Warning: Only use Peterson Cartridge Co. casings in firearms in good condition, designed, marked, and chambered for this cartridge. Do not use Peterson Cartridge Co casings for “fire forming” or any other purpose other than what they were designed and tested for. Peterson retains no responsibility for the enclosed casings if they are used outside of the manufacturer’s recommendations.
