Thread: 7mm-08 reloads extraction issue - thoughts please

What I cant get my head around, thick as I am, is that a round that is incorrectly sized for a given chamber would show that with difficulty chambering. If a round is successfully and normally able to be chambered and fired, the brass THEN conforms to the chamber dimensions and so whatever size it went in as becomes irrelevant. Surely?

From experience with 9mm and 45acp reloading, incorrect resizing of brass causes malfunctions for chambering, not extraction once fired. I have a small base 9mm die I was sold when I bought my Shadow but have never used it as chambering has never been an issue with that particular handgun.

But if there is something diff I should know about a rifle chamber please educate me..seriously.

If.someone wants to risk lending me a small base 7mm-08 die I'd happily pay the postage. Or maybe I should just buy one. It won't solve the problem tho if it turns out factory ammo gives the same results.

If you are wondering why the cartridges chamber OK but difficult to extract... physics textbook and the bit about Archimedes and levers/leverage.

After the case has fired, you don't always get sufficient brass springback if the fit was tight to begin with.
