I shot a few hand-loads through it yesterday and my results were not especially good, though that's probably due mostly to me. I have medium/small hands, but so far have found the grip to be pretty small and hard to get a good 2 hand hold on--gonna take some time I guess. Firing a moderate 130 gr accubond load I'd say the felt recoil with this brake (which really isn't very good in terms of reducing felt recoil) is maybe just a bit harder than that of a stout 10mm but less than that of a 44mag through my Blackhawk, not bad at all.
