akjeff,
I really like the caliber. I hunted with it last year. I shot a fallow deer at about 140 yards one shot kill and a whitetail deer. On the whitetail I didn't do a great job but the bullet took him down with a follow up shot rather easily.
Here's a link to Steve's reloading pages if you don't already haave them.
My double is a Krieghoff, I really like it and am impressed with it's function and reliability.
