Getting a Mag bolt face Mauser, 6.5 magnum ooorrrr

[Romeo458]

A long range 458 Win Mag.

I already have an African rifle styled 458, but a tacticool long range would be unique. It would be a sledge hammer at long distance, and I don't mind recoil

A 6.5 Magnum would be a good long range choice but I have nothing for that besides 6.5 Grendel stuff. No brass or dies.

Any other ideas for this thing?

Just throwing this out there, I’ve not spent hardly time researching it, and will likely never own or build it. Buuutttt……..
A 9-10lb. .375 H&H (or Ackley or Wby.) in a McWoody set up for hunting, but with a twist and magazine set up to support bullets set up for longer range shooting would be fun. A normal hunting style scope but with a mil or MOA reticle for getting out there.
Just a thought/passing fancy……

300 weatherby magnum is looking interesting too
