I have the same gun and with 275 grain Barnes, they are very manageable. When I shot it again after a long hiatus I was impressed at how little it recoiled with that load. They are loaded well above factory velocity to the best accuracy which is also not at the top of chart. I also have a 5.5" Redhawk (that I'm selling on gunbroker) that has a much sharper and stinging recoil with 200 grainers and the factory grips than my 500 with 275's. I can't tell a lot of difference between the Barnes 275's and 325's but in very limited load evaluation, the 275's shot a bit better in my gun so I am using them mostly. They would do the trick for any game in North America, but for big bears I'd use bigger: probably try the Barnes 385's. The 440's are nasty and I see no reason to use them. I have a box with five out, that I'll shoot up someday just for the brass. Or let somebody else do it. There's a guy on ebay selling 700 grain cast bullets for the 500. Anybody buying those is certifiably nuts but when loaded with a reasonable load the 500 is very shootable and very accurate. It's a great gun!
