Peterson 6.5 Creedmoor Fat-Neck Unprimed Brass Rifle Casings
Some competitive shooters prefer to turn the necks down on their casings to precisely fit their chamber. So Peterson Cartridge came out with a casing they call the 6.5 Creedmoor Fat Necks. These cases have a neck wall thickness of .016.
(Peterson normal necks are .0145 to .0147. The max neck wall thickness to stay inside spec is .0152 per side.)
The thicker walls on the Peterson Fat Necks allow you to trim off up to .002 per side to achieve exact uniformity. So if you are one of those shooters who likes to turn down the necks for a nice snug fit against your chamber wall, to minimize gas leak and maximize accuracy, these Fat Neck casings are for you.
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.
