Thanks all. I to use Starline brass if I can but in the times we have right now I felt like I won the lottery when my local Scheel's got brass in. There is no chance of me ever using 40S&W in it, that's why I reload so I don't have make do. I guess I was more concerned with putting the tapper crimp on. I know that we are talking only a handful of thousandth with all the cases but I wasn't sure if that will change the grip on some. I plan on using this mostly for plinking fun with some deer hunting thrown in. Again thanks for the help. Peter

I'm fairly new to loading for semi auto pistols. I just bought some Win. 10mm brass, after mic'ing about 30 or so i found they are from .885 to .896 and I was just wondering 1. What is the minimum  length you should trim them to and 2. Should I trim them? I just bought a Kimber Custom II. Like i said I haven't reloaded much in semi auto, I reload for single shot or single action pistols mostly although I do have a 22tcm (semi auto) that I load for and is a hoot and a half to shoot. Thanks for any help. Peter

I just bought a Kimber 1911 Custom II, 10mm, I'm  planning on shooting PC'd cast bullets. My question is what size mold should I get. I did a chamber cast and it came out at .403, if I go the 1 or more thousandth over that, will that be to large. It just seems over sized since everything I've read about 10mm's is they are .401 - .402. I'm assuming that's for jacketed bullets so .405 +/- seems big. Any help will be greatly appreciated. I've never cast bullets for a semi - auto. Lots of other types but not a semi. New to this site but glad I signed up. Thanks. Peter
