[QUOTE="Glocktogo, post: 931884, member: 1132"] The gun headspaces off the moon clip, not the rim or the case mouth. Moon clips can be an issue, particularly if they're dirty or bent and varying rim thicknesses can play hobknob with the ignition and cylinder rotation. The effect of the hammer hitting the cartridge, which then hits the moon clip, which then hits the cylinder face can set up a dead hammer effect that reduces the overall ability of the firing pin to ignite the cartridge. That's why so many 625 competition shooters do a lot of work on their guns. I probably had about 25 hours of gunsmithing and testing to get mine to reliably work through a 300 round practice session. When I first got it, it was lucky to make it through 60 before the cylinder started dragging and ignition problems arose. Couple that with the need to come up with a load that doesn't beat up the shooter for those 300 round sessions while maintaining consistency and accuracy and it was more trouble than it was worth. I guess for the guy that goes and shoots a box every now and then they're ok. It was the most miserable gun I've ever run in competition though. [/QUOTE]
