147g power coated
3.2g BA10
Running at 1200 rph on a RL1050 w/a Mark 7 X last night and this happened.
The digital clutch kicked in, but I have it set relatively high, and there was a loud bang (not primer detonation, more like a mechanical release).
It knocked the bottom rim of about 40% of one spot on my 9mm shell plate. It was the decapping/sizing position, #1. The case that was in that spot was fine, with only a slight deformation of the rim.
Took everything apart, couldn't find anything wrong. Re-assembled everything, and ran another 50 rounds, 1 at a time, skipping that spot on the shellplate, and it ran fine.
I've owned this press for about 15 years and loaded easily a million+rounds on it. The gentleman I bought it from was the original owner, and he was also a competitive shooter, so I'm sure he'd loaded a ton on it, too.
I ran pretty well for me up until this incident. Never anything like this.
Any ideas what happened?
I ordered a FFB shellplate just a minute ago. Hopefully that will work for me and this will never happen again.
