Arizona,
I own a Krieghoff double rifle (ss) with a set of 7x65R barrels. When I shot it with the factory loads the gun was regulated for I was less than impressed. Even though the Krieghoff allows regulation side to side on this set of barrels I wasn't able to get it right.
I don't handload so I couldn't do anything myself with it. I called Superior Ammo and they worked up a load for my gun.
I have to admit the gun now is a tack driver. It's capable of the same accuracy as any of my bolt guns. The gun now shoots as well as I'm capable of. I really like it a lot. The extra weight of it was worth carrying as I have a ball hunting with it.
