I thought the same thing about the 375 Win, wanting to buy a barrel for the Encore.
WTB: 375 Winchester barrelFinding the only likely option was a custom barrel (for 375).....then checked into the 460 S&W for an Encore barrel. Around 2900 fps for a 200 grain Hornady bullet.
460 S&W Encore 20 inchThe guy was resting his barrel directly on the sandbag.....no-no for group, fine for chrono only.
Anyway, after pricing the 460 S&W stainless barrels at over $300, settled on a $425 Ruger American Ranch in 450 Bushmaster. .450BM shoots .452 bullets......same diameter as the 460 S&W.
Most factory loads for the 450BM are 225-260 grains (at around 2200-2300 fps). Would be interesting to see what a handloaded Hornady 200 grain FTX would do for muzzle velocity.
I also suggested my .375 Win would be a great option. Had it at the range yesterday and was blasting clay pigeons at 300 yards at will and pinging the steel at 500.
