Anybody running the 195 in a short action SAMMI chamber with any luck? Picked some up for a decent deal and looking for some guidance. I see a lot of guys running them in long throated long actions but hard to find any data on them for SAMMI chamber. That probably answers my question in itself but thought I’d ask anyway

I am interested in the same set up. I wonder if a twist rate faster than 1-9 would help accuracy in this heavy for caliber load. ????
 
I ran them in my 7SS (essentially the same) and could only get them going 2800 FPS using R26 before pressure. I can get the 175s in the 2950-2980 range and after comparing in the calculator the 175 was just a better preformer
