.454 sure seemed tame out of the big X-frame...I felt a noticeable decrease in recoil when I'd switch from .460 loads. They're still pretty loud, though.
+1 on ALWAYS wearing hearing protection. After dropping a grand on a fine revolver like the XVR, I'd pony up the cash for comfortable electronic muffs for hunting like the 24db NRR Walker's Game Ear Quad muffs...I haven't tried Peltor or ProEars, but have heard good things about them as well. One to two-hundred bucks at Midway/Cabela's/Bass Pro should do the trick...and they're all on sale right now
Even with my melon-head, I can wear my Quad muffs all day, they amplify ambient sound, and I can hear directionally...directional hearing is a must in my book, if you're a serious hunter or happen to be in an area with dangerous game. When I'm at the range I will double up with some plugs too.
All I can say is...don't use plugs and hunt deaf, and definitely don't make the mistake of shooting that cannon without protection...all it takes is one shot with that thing and the ringing silence will be with you a lifetime. Best wishes to you.
