So I got a new mold RCBS 45-201-SWC and did a little reloading after thanksgiving dinner as I cast these a couple weeks ago and tumble lubed them with some alox. I loaded them over 4.6 grains of hogdon clays with Winchester large pistol primers. Well today I went to the range and did a bit of shooting and wanted to try them out to see if I was going to have any leading issues using the hogdon Clays and out of 4 groups at 25 yards I shot 2 that were both slightly more than 1 1/2" and the other 2 groups were a little over 2"(those 2 groups were shot one handed). That wouldn't be surprising if I was using my match 1911 but I was using my beretta px4. These seem almost like a fluke but it was 4 groups of 5 rounds each. I'm not trying to brag but I'm seriously starting to wonder if that range is really at 25 yards, I plan to call them tomorrow just to confirm. Is it Normal to get such small groups out of cast bullets like this? Has anyone else had this kind of accuracy out of commercial pistols that aren't match quality? With cast bullets can you get the same out of say a glock or an XD?
if you look at the picture it got turned sideways but if you look at the target on the left side the rounds in the bull and the one touching the 9 ring line are from my hard ball shooting at 15 yards. The ones just to the left of the bull are the SWC's and that one guy to the right of the bull(my lu lu). These rounds are shooting a hair to the left apparently.
