Just took my new 300 wsm carbon classic out to break in the barrel. I purchased some nosler trophy grade 180 ab ammo to do the break in and harvest the brass. From the first shot I noticed a fairly hard bolt lift, after inspecting the case there where two very pronounced rings on the case head from the double ejectors. The primers were slightly flattened but not too bad. I did t notice any cratering. I thought it was a bit odd, but continued to work through a couple shots and cleaning. Same thing every time. I guess they are some hot factory loads. On at least one of the shots I took, the bolt lift was hard enough I couldn't do it while keeping the rifle mounted to my shoulder. I've heard that nosler brass can be a bit soft? Does anyone have any experience with it? Do you think I should just buy some Norma brass for my hand loads? I'm guessing that the gun may have a chamber on the tighter end of the spectrum? Does that sound right to you guys? May just be a fluke, but I guess I better really start slow and work my way up carefully once I get to hand loads.
