Home Forums Hunting & Shooting Express Rifles and Big Bores Only Winchester 70 458 build

I switched the bolt from the .458 WM+ M70 Classic into the .270 WCF M70 Classic that has 3.6" box, shortened ejector, and .400 WB chamber.
The XRM box allowed 4 down and closing of the bolt.
I used four .458 WM+ dummies at 3.57" COL.
The .400 WB chamber is big enough for the .458 bulleted dummies to start into it.
The rails retained and the dummies fed.
The rifle ejected them with room to spare as the bullet tips swing by the right side of receiver ring.
This is with the action having the long rear bridge.
There is no impediment to thumbing cartridges into the magazine either.
Start either the rear or forward end of the cartridge into the action and it just falls into the magazine.

Having known for years that all my unaltered .458 WinMags on the .30-06-length actions will eject unfired cartridges up to 3.54"
I never even thought about using a .30-06-length action with shortened ejector-bolt-stop and lengthened box
for a .458 WM+ and 3.6" COL.
DOH !

This concept is going to get some use.
Why weaken an M70 Classic Connecticut or FN-made .30-06 rear bridge to .375 H&H rear bridge ?
