So far I haven't seen what your black powder load will be? I have shot up to 120 grains of FFG Goex in both my 45 caliber slug guns and have had no serious issues with recoil. One weighs 16 pounds with the scope and the Pedersoli Gibbs only weighs 12 pounds due to international rules and it "jumps" more but not a whole lot of kick. Sort of like a 12 gauge with 3 inch shells I guess so that one should not be too bad. My .58 bore under hammer with 90 grains of powder kicks a bit more but it only weighs 10 pounds. I guess the rifle's weight has quite a bit to do with recoil as well as the weight of the chunk of lead going down the barrel? If it were me I would start with 80 or 90 grains of FFG for a couple of shots to get used to it and then go up to whatever Pedersoli recommended. Their documentation seems to be pretty accurate.
