Black powder is more of a "shove" instead of the "punch" of smokeless.

Recoil is subjective, but unless the gun is very light or there are health issues involved the load of 80 grs of FF and 1 1/4 oz of shot shouldn't be too bad.

I routinely shoot 1 oz of shot and 80-100 grs of FF for cowboy shooting (CZ Bobwhite G2, factory pad) and I often use a 10 gauge with 120 grs of FF and 1 1/2 oz of shot. That's a firm shove, but not painful. I will note that the 10 gauge weighs 12 1/2 pounds and has a oversized recoil pad. I have had several women cowboy shooters volunteer to shoot the 10 gauge and I got big smiles out of all of them and no complaints about recoil. One woman said it kicked LESS than her 20 gauge (Stoeger or Stevens) with factory ammo
