I have noticed that federal brass looks nice but is rather soft, on 300 win mag get 3 maybe 4 reloads. Winchester brass I've got some going on 5 to 6 times, with no primer problems and no neck cracking. Can't stand hornaday terrible lots of primer problems. Had good luck with Lupua, Nosler but it seems to be little soft. Also use for 308, and 270, 300 was. Overall when I can get Winchester brass that's what I like.
