So I loaded up some hollow point cast from my new 45 200-225grain mold. I went o the range to shoot them and see how the accuracy was and it sucked. I shot these at 10 yards off hand and they were landing 3" high and left of my normal POI. They grouped 1.9" center to center at the best. I shot them off a bag at 10 yards and it wasn't much better. I shot these out of my Beretta PX4 .45 on a nice day so what in the world. Below is all of my load data for the boolits. The ones loaded up with Clays performed slightly better but nowhere near as well as my 200 grain semi-wadcutters loaded with Clays at 3.8grains in the same gun. So my question is what the heck is going on? I know I had about 1 in every 20 didn't want to feed all the way and had to be nudged into battery. My best guess is that maybe I should try them sized to 451 and see if that's any better. I will slug the bore before I try that. What variables should I start adjusting to make this boolit fly right. Also there was no key holeing. The boolits were filled out very well, the bases were clean and neat. Could my round size be too soft by chance causeing boolit skid. I noticed the other day that some of my lead ingots got mixed together when we moved so it could Ben more pure lead than I thought.
