Re: Brass At The End Of Its Life
Posted: 08 Nov 2015 09:52
I'm very stingy with my brass especially in slightly exotic things like 264 WM . I only shoot the exotic carts in 1 rifle so so there's no need to full length every time.
As a little side note the belted mags like most rimmed cartridges are designed to head space on the belt not the shoulder . This also allows weird things like a clearly marked 7mm Remington mag to be left on the range with very distinct Weatherby shoulders . The end result is case stretch and the separation you're seeing . If it were me I would use 2 different brands and size the minimum needed for each rifle such as Remington LRP for the 7x6.8 mildcat and SRP brass for the 6.8 SPCII. Annealing necks goes a long ways in making brass last a long time. I had some Winchester 45 Colts that was smoking cases with a load into Ruger loads . Turns out you can neck size Colts cases and anneal them ,those are going on 40 or so cycles . The 264 WM has cases that 5 cycles on them and are yet to reach trim length ,honestly though those loads are at a paltry 2900 fps with 140s . So it's really just being shot at an 06' levels.
