Which .458

[rickiesrevenge]

I'm building a .458 on a short action m1999. Magnum bolt face and a mag box that allows 3.1" loaded ammo. Seriously considering a 458 B&M if I can make it happen. I have a .458x2" reamer on hand already so that is tempting. Honestly I will likely never make it to Africa but I live in Alaska and can see the rifle getting used for grizzlies a lot.

Are there any other .458" cartridges that I should consider?

I built a 450 Marlin in a bolt rifle! Boyd’s stock and Ceracoted makes it a great all weather tool.

My latest .458 is built on a Ruger M77 Mark II Stainless action. It started as a 7mm Rem Mag, but I rebarreled it with a 20" Jury #4 and added NECG sights and mounted a Leupold VX-R 2-7X33 IR scope and an Alaska Arms Coffin floorplate to get four rounds down. In my opinion, just go with a SAAMI .458 Win Mag... it gives you the most options.

Cant fit a 458 into a 3.1" mag box so its not an option.

450 marlin would be a good option except mthe fact that getting brass or ammo is super tough these days.

Just go with the 458 B&M, looks ideal for your action length.
The 458WSM is another option, but ballistically inferior to the B&M.

Bertram still makes 450 Marlin brass. I think one of the members on this site was negotiating to become their new US distributor.
