One of my internet friends has one. [458x1.8] Very impressive loads. He uses Hornady brass and Hornady 458 dies.

My brother has a .452x1.8, he uses W/W 458 Win Brass shortened.

With a case full of H4198 it will send a 250 FTX at 2600 fps. Same load should work for a .458 Bullet.


Get close and wack em hard!
