Ballistically, none.A little less velocity actually(100fps or so). Mechanically a bit. A little better barrel life too. It fits a short action better....as in you can use the long bullets and not seat deep into the powder collum. My 6XC is a Surgeon 591,(700 SA footprint)running AI mags. My COAL is 2.770" with 115 VLD's. The bottom end of the bearing surface is even with the neck/shoulder conjuntion...allowing me plenty of space to "chase the lands" as the the throat wears. No donut worries either..

Norma makes the brass for David Tubb and it has to be purchased through Superior Shooting Systems. I bought a lot of 500 from them and the quality has been excellent.

I'm kicking around Bob's idea of a lightweight XC....That would be a dynamite antelope/deer/coyote rifle.
