rgh2, Based on what I've read on this thread, go ahead and load light 2 3/4" loads roll crimped in a 2.5 gun. They certainly work for me, for what that may be worth. Of course you know what assumption does. As to pressure testing, alas, no B'ham Proof House readily available for those of us in the colonies that I'm aware of. You can, however, have your loads proof tested for pressure and velocity. Contact precisionreloading.com, cool guy. He does--at least did---offer proof testing of your ammuntion for $45. In addition, he offers lots of shotgun handloading components, some of which could be useful to you.
Good luck,
Steve
