jrmoore, That is very interesting, I know that just tighting the sizer die down will drive the shoulder back and do little to reduce the base diameter, But I tried it just the same to see if it would cure the extacting problem, it didnt, so Im wondering now if you are right and my chamber is just a little tight. I should say that the brass that I am using is older brass that I have had for a while and it was originally used in a bolt action 30-30 that I no longer have. I would think though that my resizing die would size the casing back down to specs. I should start out with some new brass and see what effect that has on this situation.
thanks joe
