I have a Talo Trapper in .357 Max with the 18 3/4" barrel. I'm getting 1900 fps with the Hornady 180 gr. SSP bullet over a near max load of H110. It is an honest MOA shooter, and the deer I hit with that load last year didn't complain...dropped at the shot, folded over backwards like a taco shell and never flinched.
I'm getting 2450 fps. with the 140 gr. FTX and H110, but that is seriously beyond what the bullet can handle. I'm just waiting for an armadillo to step out so I can do some "in the field testing" of that load!
