I bet it would shake that Smith apart, Snuffy. I bet it would...
I was about this close ----->||<----- to buying an H&R Handi-Rifle in .500 S&W last year. Then, I started digging a little deeper, and found that a lot of owners were actually shaking action pins lose and beating the barrel lugs to death with 575-750 gr bullets. And, even the shooters sticking with 350-500 gr bullets were having enough issues to make me abandon that idea.
I went with .444 Marlin, instead.
And, what did I do? I promptly designed a 430 gr bullet, with the goal of pushing it to 4,000 ft-lb (2,047 fps) and 5,000 ft-lb (2,289 fps) load levels in a 6.5 lb rifle
. Idiot....
(The rifle hasn't made it past the 3,650 ft-lb level yet, though (~1,950 fps). The scope keeps shaking loose under recoil. ...which is rather, um... brutal.
