I made a bunch of .45 ACP rounds with 6.1 grains of Unique. I used new Starline brass. I was careful about the charges, but I decided to weigh the cartridges anyway.
I found the vast majority weighed 320.0 or 320.2 grains, using a scale accurate to within 0.2 grains. A little under 10% by my guess were under or over by 0.4 grains. Some were a whole grain low or nearly a whole grain high.
My question: should I have concerns about squibs or overcharges? I think I'm fine because the brass itself, while surprisingly uniform in weight, varies within a range of about 0.8 grains.
My powder measure is very consistent, I'm very careful, and if I get interrupted, I pull cartridges that could be affected and run them through a second time.
