RE: Cast Bullets for 458 Win Mag?
My buddy found these in the old Lyman Manual These are for the 552 Grain #2 alloy. Unique 16 Grains 1050 FPS-20 GRAINS@1200 FPS. NEXT IS 2400 POWDER 23 GRAINS@1100 FPS-29 GRAINS@1330 FPS imr 4227 39GRAINS @1555 FPS-45 GRAINS @1705 FPS imr 4198 48GRAINS@1690 FPS-52 GRAINS 1810 FPS. imr 3031 56 GRAINS@1745- 65 GRAINS @1980 FPS. imr 4064 59 GRAINS @1730- 67 GRAINS @1955 FPS.
Hope these help you out. He recommends the Lyman manual for cast bullet loads. He Emailed me this data. This is not something that I have tried. Might be a good guide line.

James B,
Thank a million for chasing down the info. It looks good for what I need. I will also try to find a Lyman manual. I'll let you know how things work out.

You might also check the Accurate #2 book. They have cast bullet loads for the .458 Winchester Mag in 400gr., 475gr. and the 500gr. roundnose bullet. Also some with gas checks. The 500gr. roundnose shows a starting load of 42.3grs. of 5744 for 1672fps., max load of 47.0grs. at 1901fps. with 49,900 CUP. I've always liked that 5744 powder. At 1901fps., that's moving pretty good for a 500gr. cast bullet. Better have some good lube or a hard cast bullet.
