Here's the question (problem); After shooting a cartirdge several times, I'm having trouble with with the cases not chambering and the problem seems to be lower down on the case, not the overall length or the shoulder length. So I need to resize the case, but would prefer not to resize with the standard resizing dies which will also bump the shoulder to a deminsion which is not right for my rifle. Just want to resize the sides of the case, not the neck or the shoulder, but can't find a die which does that.
Does this make sense? Anyone have any thoughts, especially a die which will only resize the sides of the case and not bump the shoulder?
Thanks in advance!!
I think you answered the question in your post.
* take a case fired one time, and look for the bright ring forming just above the base. Now take one of your cases that won't chamber and measure the diameter at that ring on both cases. If there is much more than .0015" difference, you need to back your load off a bit. If the cases are identical, then I'd be doing a chamber case. You may have an undersized chamber, or a short gauge line deminsion.
* now you should bump the shoulder every so many firings (will vary per
. Some are every three rounds and some may eight to ten. Also it appears your trying to partial neck size with a full length sizer. I know folks that have tried this in the past, and all gave up on the idea
