A comment from someone who actuall has a 460. I realize that it shouldn't matter, but it does. Stop shooting the 200 grain bullets. They are too light for this gun. I dont shoot anything less than 250 grain and the gun really prefers 300 grain. And yes, send it back to S&W for repair. As to comments about getting a 44 mag because it's more "practical" - screw that. I shoot a 460 "because I can"! Dont need much other excuse.
