I have a Krieghoff Teck combination gun in 12 gauge and the unusual rifle caliber of 7X75R SE vom Hofe. With a full length insert barrel in the shot barrel in caliber 6X52R Bretschneider, I have a close range/long range combination that's hard to beat.

The vom Hofe propels a 175 grain Sierra bullet at 850 mps. (2789 fps.) and the Bretschneider moves a 100 grain Nosler at 773 mps. (2536 fps.). The Bretschneider cartridge is simply the .22 Savage High Power (5.6X52R) necked up to 6mm or the .25-35 Winchester (6.5X52R) necked down. The vom Hofe is the 9.3X74R cartridge necked down.

This combination gives me a choice of loads for either long range or short range and cartridges which are perfectly adequate for the locat whitetails.
