[QUOTE="liltank, post: 360556, member: 13275"] Well here is the story, and mind you each rifle is different. My cousin tried the listed max load for Varget. With a 168grn Nosler Custom Comp bullet @ 46.0grns should be safe. Well the first three shots resulted in crushed primers and a sticky bolt. Those three cases then were useless because the primer pockets were stretched. He ended up backing off quite a bit and found accuracy at 43.8grns and has fired them and reloaded them several dozen times with annealing the necks to keep them from splitting. I have Winchester casing doing the same thing. I over pressured and now they are in the junk brass bin. I am very careful to load now with doing pressure testing. I load one round at a time starting with say: 40.0 grains up to 46.0 grns in .5 grn increments. I then shoot one at a time until I start to see unsafe pressure signs. Most of the time I just have the chrony set up to see speeds and find my max load for that rifle. Once I find something I like, then I go back and load groups of 3 in weights I want to test. I find this method easier on brass and less ruined if you go too hot. Tank [/QUOTE]
