I own two drillings, both Krieghoffs. One is 16x16x 8x57jrs, and the other is 16x16x 30-06.
That 8x57jrs was made in 1935, and the 30-06 i bought new in the early 80's, both shoot excelent!!!!
I've taken everything from coyotes, bear, blk tail and white tail deer, moose, havoilna, ducks, pheasants, ptarmigan ect. ect.. .. with the old one, as i've drug it all over the Alaskan bush and some of the lower 48 too.
Both of my drillings are scoped, and have accessories like Krieghoff insert bbls... ect...
Here's some normal groups from the 30-06 bbl...
