I just started reloading 2 days ago, and I shot my first batch of .45 ACP today. I made 50 rounds just as a test using 230grn FMJ, 5.5 grains of Unique and CCI primers. They functioned flawlessly in my SIG P220 without so much as a hiccup. I shot some factory UMC 230grain as a comparison and what I found is that my reloads are much more accurate. I was getting like 2inch groups at ~50 feet with the reloads and like 4inch groups with the UMC rounds. This was using a pistol rest. I do think that I will try a hotter load in my next batch (still well within safe limits).
I loaded these on a cheap (inexpensive) Lee 35th Anniversary Reloading kit. This is fun.
