what kind of velocity are you guys seeing with the 175grn??? is there such thing as a velocity wall?? where if you keep going lighter you don't gain much velocity?? What I am looking for is a potent long range mule deer load, flat shooting is paramount but it also needs the energy at extented ranges, with that said how will the 175 perform out to 200+yds??remember we are talking .50 caliber guns only. right now I have some 200 grain shockwaves shooting into 1.5moa with 120grns of T7, I may just go with that but I would like slightly more accuracy.
