Can anyone tell me the cause of this? I have been reloading for about 15 years and this is the first time I have had it happen. I'm guessing it the spacing set on the resizing die?? Thanks for any info.

Need pictures

It looks like your die is not set up low enough to get a full length sizing.

Thanks. I will asjust and see if I can fix it.

That is the difference between your chamber and what you are sizing...seems awful large but I'm not used to SAMMI spec'ed chambers so don't listen to me about that being to much clearance. I'm typically working with about .002 - .003 clearance around the necks.

Well, that was it. Don't know how it was off but when I looked and saw that it didn't even come close to the shell holder, I adjusted and sized a few. Thanks for your help

good!
