My .460 is on a Brno 602 action that was originally a .375H&H. It has a Douglas barrel and is topped with a 1.5-5 Leupold. I don't recall what modifications the smith performed to the action for the larger cartridge as the rifle was built for me in the late 80's. I load 112gr of H-4350 for 2360fps with a 500gr Hornady soft. The rifle goes 10 lb empty and is a pussy cat to shoot. I have never shot any factory loads so cannot comment on potential recoil.
