Guys did anyone ever go ahead with a 458 based off a larger than weatherby but smaller than BMG sized case?

Eg OK/gibbs necked down or the 408 CT necked up to .458?

I'll take that as a no

the 45/50bmg has been done.. reaility is that people can't take the recoil levels that those would make.. rob and john did a 45/600ok ... barrel cooker, and requires a very specialized actio

All 50BMG neckdowns are barrel cookers and that's why I am not interested in them. Recoil is okay if you stick to the anti-material platform though.

The 458/600 is borderline case capacity for me,
but for sure I aint interested in too much work.

Surprised no one necked the 505 down or 408CT up yet...

Karl.

There is the 475 royale , a gibbs to 475 ... to me, its econmoics .. i can get all the recoil i want from a cheap case ... and i guess if you followed the gibbs evolution back up, the 577 NE to 577/500 to 505 gibbs ... i bet somone tried a 577/450 that wasn't the musket round ..

bet the 45 caliber ban under the british flag had something to do with it
