Sounds like there is a rough zone or some crud in the chamber. Clean and inspect. If you can see an anomaly you could put some JB on a tight fitting patch and use a hand drill to clean it up.

Re: fired cases sticking in chamber

How many firings on the brass?

I had an aawesome 7 WSM that fired everything in to a bughole and functioned perfectly until the brass had been fired 2X or 3X and then cases didn't extract from the chamber. The went in just fine and showed no pressure wehn going off, but simply didn't extract. They had grown just enough to engage the lead and wouldn't come out of the chamber. Trimeed the brass and back to no problems.

if the smith didn't mess with the chamber, it seems odd that it would develop scuffing at the belt. either way, it frustrating as heck and I hope you figure it out. When you do, let us know what it was.

Re: fired cases sticking in chamber

Just thought I'd give an update on what I figured out with the 300 win and the 7mm rem mag. Thanks for all the input and help, finally got it figured out so hope this can help someone if they come up with the same issue. The 300 win mag that was sticking the shells was a simple fix in that I backed the bullet of the lands a bit. Must have been causing some over pressure with the bullet at the lands. I have been working on a 7mm at the same time for a friend and was having the same problem. It's a factory Remington. With that one it turned out to be a rough chamber. Gunsmith polished it and it's shootin great. Thanks again

Re: fired cases sticking in chamber

Thanks for reposting what you have figured out. My STW has still been doing the same thing, but only with 1 particular load, and I think I'm gonna try it with it backed off the lands a couple thousandths, to see if that helps. My load shouldn't be THAT hot, since alot of folks are getting much more velocity with the same bullet, and alot higher powder charge, so I was figuring something had to be causing it.

Thanks again for posting back to let us know. I will try it to see if that helps. I still might go have my chamber polished by the smith. It looks to have some rough marks about 1/8" above the belt, where it's sticking in the chamber.
