Yea the one I shot kicked like my Ithaca Deerslayer with slugs in it .. and that had recoil !!!
Not sure the powder charge he was using ..
It wasn’t unbearable and I’ve shot far worse , but with my shoulder I’d rather have it softer .
Thats why I asked about a 45 vs 50 .. so if a 50 with sabot is actually a 45 bullet , what is a 45 cal with sabot ? A 40 cal bullet ?
