I got distracted by a primer feed failure and then turned the shell plate on my RL550B when I shouldn't have. I dumped a cartridge that hadn't been crimped. I immediately realized what I'd done and stopped. Unfortunately, the finished cartridge bin already had nearly 200 rounds of 9mm in it. I figured no problem, it's got to be one of the "top most" rounds in the bin...so I started carefully removing cartridges and examining them. I thought it'd be no problem to find the uncrimped one...but I can't find it. All the cartridges gage just fine. Measuring crimped and non-crimped rounds, the typical difference is only around 0.02". At this point, I think without using the calipers on 150 rounds, I'm not going to find it. I thought I'd be able to see it just by looking down on all the rounds...but nope. This is a batch I was loading for an IPSC match this weekend. What's the worst that would happen if I shoot the non-crimped round? I'm guessing as long as it chambers, it'll shoot just fine...perhaps a tiny bit lower velocity, but I doubt even that.
