If so it could be that you just have a strong spring on the plunger / ejector.
The dimensions will be the same but theoretically the “grip” will be different. It would be interesting to chronograph some of those round and compare velocities. The unlubed cases should develop a little more pressure and therefore have a slightly higher velocity.Yes that’s what I think too. I need to borrow a Lab Radar and compare.
If you remember when we started the polishing of necks and dry lube seating you do get aboit 12 fps faster speeds.
I still polish AND dry lube, seems to give me the most consistencey in es.
Hope this helps.
