Guffey,

Here is how I used my Hornady "comparator":

Measured unfired, new factory case in the "comparator" installed on my calliper.

Measured fired case the same way. Fired case is 0.003" longer to shoulder datum than it was before fireing.

Screwed FL die into press until it touched fired case, then began adjusting die down and measuring case length to shoulder datum with "comparator" until the case was 0.002" shorter. Set lock ring on die at this point.

My question to you, as you seem to know these things, is how do I make a "chamber length gague"? Please be specific so as I can benefit from your knowledge. If I lived nearby, I would bring the rifle to you and you could explain it to me, but no such luck.

Also, this still hasn't answered my original question about why this individual rifle is doing this to my brass! Are you suggesting that my chamber is oversized? I am a simple man and need simple, straight forward answers. Thanks.
