Well, now I'm more confused than ever. I measured the case volume of some Federal cases (gold medal match, I think) and compared them to some PPU cases, all prepped using the same procedure. The Federal cases measured 3.48cc and the PPU came in at 3.58cc. I didn't believe the results, so I...

Yeah, it's gotta be the brass. I just tried dropping the charge down to 42.5 grains of Varget under a lighter bullet, the nosler 168 gr HPBT, and the cases still get stuck in the chamber after firing (even though they seem to chamber just fine). One thing that annoys me to no end is that...

Hodgedon suggested that the Prvi Partizan brass might be thicker NATO brass, which is causing a pressure spike due to the smaller volume inside the cases. I had heard of such problems arising when loading 5.56 brass, but I had not been aware that this was an issue when loading 308. My brass is...

That's worth trying. Until I can get some virgin brass, at the very least, I'm going to try some other headstamps.

I measured the case length before firing (pulling the bullet on a new round allowed me to verify this using a good grip with calipers) and found them to start out at about 2.005. After firing, they grow to around 2.008. The reloads were growing from 2.015 to as long as 2.025, but sometimes...

That's another good point. However, if this was the main contributing factor, I would expect to have some cases get stuck while others would cycle normally. As best as I can tell, they all have a problem, some a little worse than others, but none of them cycle like they should.

That's fair. If this was a tighter chamber and wasn't a factory Remington barrel, I probably would have worried more about the length of the case. Maybe I ought to trim a bit further to see if that changes anything.

I've looked for clues all over the internet and in my reloading books, but so far I have come up short in trying to solve a problem I'm having with my 308 loads. I've been working on solving this off and on for a few months with no luck. I have loaded successfully for years in a bunch of...
