Georgia Arms never seems to have any ammo for the 460 Rowland, or at least it appears they are permanently out.
Corbon, Wilson Combat, Buffalo Bore and Underwood all offer ammo for it! The ammo in the video wasn't even on the upper end of what this round can do.. I just got some stuff from Underwood that's suppose to hit like 1500 fps with 185 gr!
That S&W M&P 45c is a nice gun, but it cant touch this!
