It's been a long time since I shot a 7 mag and have never fired a 40-65 or 45-110. I did own a 45-70 trapdoor for a number of years and the recoil with a 405 gr. bullet with a full case of bp is akin to a 12 gauge with smokeless and no recoil pad. I would think the 45-110 would be a mite sharper and the 40-65 about the same.
