You can get away with a lot more when loading for a bolt gun or a revolver. Pay attention to the OAL and the crimp.
Pull your barrel and make sure your rounds drop in without issue. Worth loading up a few dummy's to get things dialed in.
You will also feel really dumb if you go all mass production. Only to learn that that coffee can full of 45 ammo you loaded on a stupid single stage press, doesn't actually run in your gun![]()
This is solid advice. Learned it the hard way myself, and it's part of why I generally despise the idea of "match grade" anything for work/duty guns.
I loaded up .40 S&W by the thousands for Sig 229s in the late 1990s and early 2000s. A girlfriend got a .40 with a "match" grade barrel around 2010, and less than 50% of my reloads cycled through her gun. The chambers are just tighter with match tolerances, sometimes stupidly so.
So yes, always double-check your sizing by dropping 10 or 20 of your reloads down your own barrel - if they all don't "thunk" solidly and then drop out freely and easily when you turn the barrel upside down, they're sized too big.
