I'm guessing that you have not had any experience with a Drilling. While they are expensive, my Krieghoff weighs 7 1/2 lbs. which isn't very heavy, mounting the scope adds another 19 oz.drillings are expensive to manufacture and can be heavy to carry.
They have a place in history but did not make a big success in the general marketplace.
I used to own one of those. it was a 22LR over a 20 Gauge. The only difference is that mine had the lever on the tang to break it open. Handy little gun, it accounted for a whole lotta rabbits and squirrels, a few quail and countless numbers of groundhogs. Wish I still had it. Though in 1985 I bought dad a 30-30 over 20 Guage. The 30-30 barrel will shoot inch groups at 100 yards.Something like this would be handy-dandy to have around or in a BOB!
I don't think Savage is making them but A Russian Co and I believe Rossi is. I believe you will find guns like the Savage M24 were called combination guns.Drillings were three barrels or more in multiple cal/guage. ,,,sam.Does Savage even make these guns anymore? I have a 410/22lr, but would rather have a larger rifle caliber.
