I've fired one once (belonged to another shooter at the range who was kind enough to offer me a shot). I don't know what load was involved and I'm a fairly light build. I approached it with some trepidation expecting it to kick like a mule. I was totally surprised with how comfortable it was. Recoil was more of an authoritative push than a kick. Much more pleasant than my SRH .454 Casull. Definitely a calibre I'd buy if I was into single shots.
