A 6" barrel with no venting makes a world of difference. At the top end 900fps can be reached with a .45 Super with a 6" barrel. Buffalo Bore's 255gr Super load rated at 1075fps goes 1130fps from my 6" barrel. Hadloaded 230s can hit 1350 from the 6" tube. reflex264

"A quiet hit in the right place is better than a loud miss in the wrong place followed by 10 more shots on the run"
