My factory barreled 7mm weatherby worked well with 70.5 gr. of H4831, Winchester LRM primers and a 3.5" COAL. 168 gr. Bergers. Light ejector marks over 6 firings on the brass.
After I rebarreled it, 70.4 gr. is the most accurate. 3100 fps ES of 8. sub M.O.A. at 200 yds. 168 gr. Bergers
I recently picked up some bullets made by Matrix Ballistics. He is a small bulletsmith in British Columbia. I got some bonded 175 gr. Rebated boattails, and some 190 gr. match grade bullets as well. Haven't shot them yet.
