This new ammo was clocked in 24" barrel as FYI. YMMV with shorter barrels.
So 80K alloy brass in 6.5CM rifle? I like the idea a lot and think this technology will be transferred in more traditional cartridges over time. This YT discussion is pretty good. Clean dry chamber free of any debris, oils, corrosion absolutely critical to insure the alloy grips the chamber walls and not increase bolt thrust.
Federal is going to offer unfired alloy brass for reloading soon.
Is it an elk rifle? Why not? It has the velocity and bullet construction.
IMO this new ammo cuts the manbun off the shooter....OMG! Somebody had to say it!
