I'm not exactly sure what you are asking, but I have a similar full length insert barrel in my Krieghoff combination gun, in caliber 6X52R Bretschneider. It, together with the rifle barrel in 7X75R SE vom Hofe, equips me for a full range of game, from small deer to elk, simply by choosing the appropriate trigger. The combination of cartridge and insert barrel is very accurate and is sighted in to the same point of impact as the rifle barrel at 100 meters.
