Peterson Cartridge .408 CheyTac (10.36x77) Brass Rifle Casings - 50/Box

Peterson Cartridge .408 CheyTac (10.36x77) unprimed brass rifle casings are American-made, match-grade reloaders' brass produced for extreme long range (ELR) shooters. Each casing is built to Peterson's tight tolerances and uniform wall thickness for repeatable performance across load development and match use.

The .408 CheyTac (also designated 10.36x77) is based on the .505 Gibbs necked down to .408 inches and was originally developed for ultra-long-range precision applications. These casings are packaged 50 per box, with 10 boxes per case (500 total per case), and ship unprimed and ready for the reloading bench.

Technical specifications include a case length of 77.21 mm, 10.36 mm bullet diameter, and case capacity of 10.32 cm3, rated to a maximum pressure of 440.00 MPa - giving handloaders the headroom needed for heavy, high-BC ELR projectiles. Model 40023-R.
