Here's a little tool that will help you stay in spec. They are called gauges and you drop the finished cartridge in and if it goes in flush and doesn't stick out the other end you got a shooter. The only problem I have had in the last three years since I started using them is dead primers. I have had only a few of them. .223 rifle, .45acp pistol, .9mm pistol. Dial Calipers. :thumbsup:I'm planning on reloading .40 once I start. I have like 650 spent casings... I guess I'll just have to inspect them well each time I reload. Plus my gun has a supported chamber, so that is good.
