You may have it right, ie. my wife is special with a husband dumb as a stump.

The drilling is not marked 3000 any where but it was made in the 60's and think it is the same model as yours. Sauer also made the Colt Drillings in this same style. I have handled a fair amount of drillings and so far I like this one the best. I can shoot it on flying game, ducks and doves and quail better than my Browning O/U. The 30-06 bbl is very accurate, and my wife has even killed a pig with a slug.

I have not had any problems with extraction in the 30-06 bbl.
We use the drilling on our lease in Texas, and on bear/grouse hunts in Montana, and in Sept I took in on my Idaho Bear hunt and shot a few grouse with it.
I had www.murrayleather.com make me a buttstock shell carrier with three 30-06 and three 12ga shells.
Very handy, his stuff is worth every penny.
