[QUOTE="Veteran, post: 2467958, member: 118038"] Just changing brass can be a BIG DEAL! In the example Carlos gave, he only had a 4.1% diff in case volume. In my .338 LM, my used Hornady brass had a volume of 107 gr H20 but my Lapua brass was 114! 6.5% difference...... 90.3 gr charge weight N565 250 gr. Scenar at 114.19 volume pressure 60789, Velocity 2887 at 107 volume pressure 71245, Velocity 2995 Kaboom..... Thats the difference just a few percent of volume in the brass.....over 10,000 psi....very dangerous. Be very careful changing brass.....its not the same! [/QUOTE]
