I recently worked a deal with Champlin Arms for a Krieghoff 500/416 double. I believe that doubles should have a rimmed round and it gives the same ballistics as the 416 Rigby/REM/Ruger class of rounds. I have had two acquaintances that have them and love them. I realize it is an unusual choice but it came with brass, dies, 120rounds of factory Hornaday practice ammo, aimpoint red dot, and a set of 20 ga barrels. I was able to get it out yesterday and shot both the DGX and DGS bullets. Both the softs and solids gave barrel groups that were touching the solids gave the best but were 3 in apart almost on the same horizontal plain. Speed in the chrono was 2245 average. The softs had about 3 1/2 in of barrel crossover. speed average was 2452. So softs would need to slow down and the solids speed up to get a acceptable both barrel composite grouping. Even with the Hornaday practice ammo I was able to solidly hit 8 in plate at 100 with both loads. The rifle was regulated with Norma OH ammo. It gives me a solid base to work from in developing a set of loads for Swift A-frames and CEB solids.
