Many Thanks, gentlemen. To add to my query, what's the word on Chapuis DRs? I have an opportunity to get one at a reasonable cost.

The only double rifles I own are an Alex Henry BPE .450 3 1/4 and an ancient Lang 18 bore muzzleloader.

Both are great rifles and well over 100 years old. I just don't know much about modern arms.

Any help is greatly appreciated.

Again, thanks for the cartridge help and leads. - Marc
