So I started by sacrificing a Jap made 2-7x35 Tasco and I discovered the rings and scope were not cutting it. Changed to a Burris FF2 3-9x40 that was spare and it struggled also
New Bergara steel picatinny rail, Warne steel ring and an old scope Loopy 6x was the next upgrade. Scope has survived and no slip detected. Energy is around 36-3800ft lbs, but I would like to bump that up to max.
Corbon have a published 400gr loads doing 2340fps from a 22 inch barrel, thats about 4863 ft-lbs, just a wee bit more than a 45-70
