610 Head Space Problems?
- Thread starter Iowahunter
- Start date
Sometimes with really light loads the primer will back out of the case. Normally when the round goes off the primer is pushed back into the case by the recoil. I found this out by accident testing different brands of primers for hardness. Every time I fired a primer (in an otherwise empty shell) the cylinder would lock up. Once I got the cylinder open I found the primer had backed out. I also found that if you drill out the flash hole for this kind of test the primer won't back out.

Make sure your primers are all seated properly. If they are not that is another cause of cylinder lock up. I reload my own ammo and shoot plates and pins. I had several instances where the primers were high and it screwed up my relay because the cylinder locked on a high primer. After that I got in the habit of pulling the hammer back JUST enough (with finger off the trigger!) to unlock the cylinder so I could spin the cylinder to check for high primers or bent moon clips at the start of the relay. If there was a problem I would just eject the offending clip and pop in another.
I know I will get grief about this from a safety perspective but the hammer block stays engaged if you only pull the hammer back just enough to release the cylinder AND keep your finger off the trigger so if you accidentally drop the hammer the gun will not go off. Of course I always keep the gun pointed down range at all times when loading or doing the check.

Your description seems to be that the primer is extruding into the firing pin hole in the hammer nose bushing/recoil plate. This has absolutely nothing to do with headspace! It needs to go to the factory for a hammer nose bushing, the hole is too big.
Never thought of that. Learn something new every day.
