Ha ha yeah that's interesting...my Uberti .36 Remington Navy is a real tack-driver for a cap-n-ball revolver, not too long ago it shot a 1.5" group for me at 20 yards. My Euro-Arms 1860 .45" is accurate, but nothing like the .36 Uberti. Them guns have a mind of thier own.
I'd go for the .36 for target shooting for sure, and it would sure make a cool little grouse gun if you are a hunter. I've always wanted that gun in .36, just for that purpose, although the Remington Navy fills that slot now.
