It happens. I used to be far more detail oriented with reloading, before I started reloading in bulk....that is going to change now. For pistol I fortunately have those Shockbottle case gauges which makes it extremely easy to check all pistol rounds. I've found a 100 round 223 case gauge, however it's extremely expensive....around $300. Depending on how much I hate checking every single 223 round I load, I may have to suck it up and buy that case gauge.
