Is my Type 2 chamber not Type 2?

It was for this reason that I kept my fired brass separated. The BHW brass is .004 longer than the Larue. Not as severe as the .010" difference between JRB's two barrels, but enough to make me notice.

With mixed brass, I would have to choose a compromise on the shoulder setback. If I were to setup the dies to bump the shoulders .003" for the BHW, the brass would be on the long side in the Larue. On the other hand, setting up the dies to bump the shoulders for the Larue would tend to overwork the brass fired in the BHW.

The working solution has been to setup the sizing die for each rifle's fired brass, and keep the brass separated throughout the life cycle of the ammunition.

However - with the new found abundance of cheap loaded ammunition with quality brass, the point may be moot. Brass life may have become a little less critical, given the introduction of the American Gunner ammunition.

This was the battle I was having with my 18"-Arp, the fired brass was too long for any other chamber so I was doing 2 dies and 2 sets of brass for a while. It happened to be an LBC-style but he used his own name for it... bottom line was it stretched new brass out to the 1.225/6 (new Hornady is more like 1.209 at the datum point) and I had to resize such that it was too long for my other, more (what I would call) normal chambers. Didn't like having to stretch brass like that out of the box. Running 2 sets wasn't really getting me any bang for the buck either, so I sold it to a guy who doesn't reload and doesn't worry about brass lengths.
