I have a friend who refuses to shoot the 'standard' bullet wt for the caliber. (ie 180/.40 s&w or 230/.45 acp) In his .45's, he always used 165 grain bullet because of the 'great energy figures'. But complains that he always has to change to adjustable sights to zero his load. I told him the sights we regulated for 230 gr bullets and the .45 relys on mass and diameter, but he get's sucked in with lighter, faster, high energy figures. If he would just pick a good H.P. 230 gr load, it would be more pleasant to shoot, would shoot to the sights, and do the job just as intended. If that is the load you intend to shoot forever, get the file out! 44 Man
