Something in that area, or perhaps down to 350 grains or so... I've had the big revolvers since S&W first introduced 'em and at this point it has always been just a range toy. Have never hunted with it.
For ammo I've limited myself to two bullets:
350 grain Hornady hollow point
440 grain Cast Performance flat nose
Mostly I shoot the 440's at about 1400 fps - which is roughly 200 fps below max. Makes for a very good load - easy to control, accurate and I think the half-inch diameter, 440 grain bullet at 1400 fps is tough enough for most chores! :grin: It shoots through big douglas fir stumps...
So I was really thinking of something about the weight of the Hornady, but perhaps tougher - like a Partition design. Dunno... The thing really doesn't seem to need much expansion.
