22-250 reloading problems
The name is shutzen, and although I've been lurking for a long time this is my first post Been shooting and hand loading since the early 50's and I have a problem that I've never encountered before. I'm handloading for a new rifle, a Howa 22-250 !500 Bull barrel. This is not my first 22-250, but it may be my last.As I only own one 22-250 at present I only necksize my cases.Therefore I only have to check my cases every reload and trim cases. What is happening is using the same dies for each case about 50% of the cases will not allow bolt closure. I trim the cases all to.2o7 col,and die form them neck resizeing. they still will not chamber. I have Mic'ed the cases and they are all the same/+- a smidgin? The only thing I have found different is on some the shoulder is a little closer to the neck. I know that will make it difficult if not impossible to close the bolt. My question is how using the same press and the same dies with a uniform stroke and pressure how can the shoulder lnngth be different? Also I use a lee hand trimmer, with a 22 cal pilot. But after necksizing, the pilot won't allow the trimmer to make contact with the case mouth. I tried a mechanical trimmer and the same thing happens. The pilot doesn;t seem to go far enough into the case mouth to let the trimer do any cutting This only happens on once or more fired cases .New cases load and fire fine. Also these loads are not max or even close altho that doesn't seem to make any differance
Has anyone ever encountered this problem? Myshooying freinds have never heard of it. In fact they had to see it to beleive it.
any help would be gratfully received..... shutzen
