In respopnse as to what I consider excessive pressure a very experienced freind sat next to me at the range. The thing I noticed was the sound of the report. He looked at the primer and it was very flat compared with the nosler loads. I have had that same sharp sounding report 2 yrs. ago with nosler brass and a hot load. That load blew my extractor and spring and ball out of the bolt of another mod. 12 22-250. I know by the sound and condition of the primer. I have been working a lot and have not checked case capacity. I did however check brass thickness on lapua vs nosler and they are identical.thanks birdie...
