I have a Tikka varmint .223 that shoots Blackhills reloads just fine. I bought some new Win. brass at cabelas last year and worked up some loads with Win 748 powder. I started at 26 g. witch was way to much for this rifle. Totaly flattend the primers on the first 2 shots. Third shot case sepparated in half! I backed down to 24 g. and worked slowly up to 25 g. Now here is the problem, after the shot the primer sticks out .027 of the brass. The bolt can't grab the case and extract it. It doesn't matter what powder charge I use. I can't even get the brass into the shell holder to reload because of the primer sticking out. I have 400 rounds of this new brass all primed and I am totaly stumped. I don't know If the chamber accepts the Lakecity brass better than this new Win. brass? Anybody have any ideas I would really appreciate it.
