Good stuff Pete, the 404gr Hammer bullet in my 3.6" mag length action 458 Win Mag leaves at 2500+ fps, it's a very accurate bullet, no load development to speak of, just worked up with a chrono and AA-2460 powder till i got to 2500 fps then went to the bench, GTG, great bullets i look forward to using in other rifles.
I know a guy pushing this bullets at more than 3000 fps from a 460 Bee via RL17
