Todays results with the drillings and combo gun were pretty satisfying !
I had the Kettner hammer drilling 16-16-10.75x65R Collath , the Sauer 12-12-7x57R , the Kerner 16-16-7x57R and the Zoli 12-7x57R with me today .
Shot the Kettner first with my new handloads using the modified 405 WIN brass at 50 yards and clocked them as well . Load averaged 1550 FPS with a 207 grain lead bullet and 16.5 grains of Unique out of the 26.75" barrel .
The sauer with the Rottewial factory ammo did this at 50 yards and averaged 2482 FPS from a 23.75" barrel .
The Kerner with the same 7x57R ammo averaged 2471 FPS also from a 23.75" barrel .
And finally the Zoli 7x57R combo gun averaged 2530 FPS from a 25.75" barrel with the same ammo .

Zoli
Shot some of my handloaded 16 gauge low pressure with 12 #1 Buck loads in the Kerner on paper at 25 yards and they shot really well from both barrels . I was surprised as tight as the thing is choked .
I tried some Winchester Supreme 12 gauge 2 3/4" copper plated 00 Buck in the Sauer and the Zoli and all three barrels proved to shoot a nice tight pattern at 25 yards plenty good enough for deer and again I was surprised .
I also tried Brenneke 2 3/4" slugs in the Sauer . The left barrel is dead on at 25 and 50 yards but the right barrel is wide right at both distance . That kinda leads me to believe they wanted you to shoot buck in the right barrel and a slug in the left barrel .
All in all a rather informative range session !
