I have a ZG47, originally in 7X64, which I had rebored to 8X64S. It is a hammer on white tail deer. I killed two with it last year. I have a German reloading manual with a whole page of loads for the 8X64S, which I will be glad to scan and email to you, if you will give me your email address. Use a PM, if you want to keep it private.

I also have a Krieghoff Neptun sidelock drilling originally in 16/16/7X65R, which I had rebored to 8X65RS. I think that it should prove its worth on pigs, with Brennekes in the shot barrels, should I ever get the opportunity.
