Sir Ron I'm loading 77 grains of AA2230 behind the 450 TSX at 3.380 COAL
And getting right near 2300 fps MV, great load, Sir John. Works in any standard aught-six-length mag box I know of. Loading longer COL you have to add more powder and pay the price.
2300 fps MV with a 450-grain CEB brass FN zips through elephant or 10 feet of bison, when shot inside of 50 yards. (I am guesstimating 5 feet of MIB test medium equals 10 feet of bison, from tail to throat.)
A 450-gr TSX at 2300 fps Mv would be a longer range option, almost as good as a 404-gr Shock Hammer at 2500 fps MV, maybe 2600 fps MV to push the envelope.
Ron aka "Rip" for Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary .458 Winchester Magnum, Magnanimous in Victory THE WALKING DEAD does so remind me of Democrap voters. Donkeypox.
