Bit of a random one here.
I'm reloading for .308 and using an RCBS shell holder. Most brass slides in easily and smoothly, in and out, no problems.
Randomly I'm getting a few cases that just will not go into the shell holder, they get about 30% - 40% of sliding in and jam tight.
No rhyme or reason to the ones that stick as far as I can see. I'm using Winchester and Remington brass, all has been shot 3 or 4 times.
Haven't measured with calipers (broke them, haven't replaced yet) but looking at the case heads I can't see anything out of place.
The empty cases feed and eject fine, the bases seem flat and comparing a good and bad sitting on the table together I see nothing out of place.
Ideas?
