It doesn't kick that bad, I have a 50-100 I load 530gr linebaugh to 1700,, and 450 linebaugh to 1960. Going to take the 530 to 1850 and see what that feels like.
I can shoot these loads off the bench, sighting in, 20 at a time sitting. Standing is easy to shoot.
This rifle being 4" shorter barrel will add a little jarring for sure but not as bad as it sounds.
12gauge is great no doubt, but nothing penetrates like a 450-530gr hard cast boolit.
My 3.5 12 gauge honker loads kicks way worse. In fact I had to go to 3" 12ga loads, couldn't take that 3.5" hammering.
