I bought some Underwood .41 magnum ammo. It's about as stout as it gets...210 gr at 1560 fps and over 1100 ft-lbs of M.E. Can a Smith 57 handle this? The reason I ask is because there is more than one person out there that says "Use a Blackhawk for stuff like that, it's too hot for a S&W." Opinions are appreciated, please and thank you.
