So with my current state of life I am trying to look at how I maximize both my guns and my reloading time/components. I tend to shoot a lot of 45 and 9mm. Thus, I tend to typically reload these calibers and have lots of componentes to do so laying around. The 45, since I have since sold my 45 Long Colt, 45 Win Mag and 45/750 this one is easy in that I am just loading ACP and a lot of it. With the 9mm, that is pretty straight forward as I use a lot of 124gr round nose bullets. I do load a fair amount of Sig 357, I used to have a 38 Super (which I hope to replace at some point) and I load 357 magnum. Now, the 357 Magnum I load a low volume of as I only use it in my 357 lever gun. The 9mm, Sig 357 and 38 super is where things get interesting. While these tend to have a slightly different profile and the 9mm tend to be 124gr and Sig 357 and 38 supers run more 125gr (which I have both of), and a round nose is pretty much a round nose. Here is what I wanted to bounce off of you guys; 9mm is .355, the 38 super is .356 and the 357 Sig, of course, .357. I am thinking that I could just use the same bullets as most of mine are either .355 or .356. Edit: Actually, I mic’ed what I have both for the Sig 357 and 9mm - both are .356. I think the only difference is 124gr vs 125gr and a slightly more flat nose 125gr which I bought for reloading Sig 357. I need to load up a dummy and see if it will cycle ok in my 9mm. Edit 2: Made a few dummy rounds and the 125’s do cycle fine in my 9mm. Thoughts?
