Re: 7mm rem mag brass
I have been useing federal and have no complaints. Still useing the 100 that I got from 5 boxes of factory loads that I bought in Sept. 2007, of the same lot number.
I trim, clean and clean the primer pocket every shot.
They have been fired then reloaded 5 more times each (yes I keep records of how many times my brass has been fired). 2 months ago I annealed all of them and then full length sised them after the annealing, usually I only neck sise.
I am not sure how many times is acceptible to reload, before I got the federal stuff I was useing winchester chrome plated stuff and the chrome stuff started to crack and split at the necks after 4 reloads (again I started with factory loads).
So, for me federal brass good winchester chrome plate not so good
