I started using a drilling at age 12. I am now 60 and have a small collection of them. I mowed lawns for two summers and saved all the money at age 12 to buy a bring-back drilling from a WWII vet friend of the family. It was a Sauer in 16ga 65mm chambers and 7X57R.
I have had a lot of drillings in my life...about 75-80...but am not rich; I would trade and sell to buy different ones. This gave me the opportunity to own and use some real great guns. I recently had a Geyger-Berlin two barrel set in 16/70mm and 9,3X74R with a 1.2X4 Schmidt & Bender in a swing mount and a second set of 20ga 3" and 243 with a 1.5X6 S&B in claw mounts; the 20ga set was done in 1982 by Fuch of Austria.
Misfortune dictated that I sell the Geyger set to help pay for surgery for a recently found condition. It was going to be a "keeper", but health comes first...I guess...As a drilling fanatic, it wasn't a slam-dunk choice.
I am in total agreement regarding insert barrels of all flavors. I had an early post-war Sauer in 16/7X57R with a full length 22 Hornet barrel and have a 22 WMR Kreighoff insert for my Sauer 3000 12/30-06. My favorite drilling is my Treibel-Augsburg 16/8X57JR w/4X Hensoldt in claws. I presently also have two Charles Daly Prussian sidelock-sidecock drillings; one in 12/30-30 and the other in the smaller frame 16/30-30.
Probably my favorite gun is a pre-war Sauer cape gun two barrel set in 12ga SXS and 12/8X57JR scoped in claw mounts. The old gun fits like it was custom made for me...another keeper. I recently sold a very nice Merkel Lux in 12ga and 9,3X74R with a 3X12X56 Docter Optics in AKAH claw mounts and same in 16/7X57R with a 6X Schmidt & Bender. I got to love them for a while, then sold them to others who "loved" ($$$!) them a bit more. As I said, it is my only way of owning such guns.
I have taken two cape buffalo with combo guns with 9,3X74R barrels, one with that Merkel drilling and one with a double trigger Tikka 512S in 12/9,3X74R. I have used the Tikka in Africa three times now, and had planned for using it on my last ever safari this September with the second set of 9,3X74R o/u barrels, but my "plumbing" didn't allow that. Plumbers (urologists) are a bit pricier than safaris, and we don't have great insurance down here, at least those of us who are self-employed and have to buy our own.
I'll tell you that those Baikal 94 BBFs are great shooters, if not exactly beautiful! I blundered into a NIB 12ga 3"/7X57R for $244.00 US at a gun show, and it is probably far more accurate than all my present and past "pedegree" guns. It isn't easy to look at and is even harder to shoot with my eyes CLOSED.
Thank you for sharing your love of combo guns with me...L2S
