Well as many of you have seen my previous thread, I was over pressure with 44 grains of varget 168 grain Berger and new Winchester brass. This weekend I switched to CCI 200 primers and started at 42 grains and worked my way up. I'm shooting a Model 7 with a factory 18" barrel. 42 grains shot just under half an inch, 42.5 opened up a bit, 43 back down to half an inch but I hit pressure. So I'm going with 42 grains. I wish I could get more out of it like most of you guys are go shoot 43-45 grains but I'll take a half an inch with 42 grains any day. How accurate do you think the Berger reloading manual is as far as velocity goes with posted powder charge?
