Biggest I've fired is a brno in 500 Jeffrey that @Friwi brought to the first big bore shoot held in taranaki. 535 gr fmj at 2400 fps makes for robust recoil. There was a video of a small ginger person firing it.
I've got a 500 3 inch black powder express and that's not too uncomfortable @akaroa1 is looking at making a single shot "super snider" based on the 577 nitro case. He's calculated the recoil at 60 ft lbs
