Ruger4Life,

Right on, right on, right on.

If a lion charged me I would probably crap my pants too.

Moving on to the next epiphany:

You do not need to shorten the bridge at rear of M70 Classic from Connecticut or FN
to turn the .30-06-length donor action into a 3.6"-COL-accepting action.
All you have to do is unblock the rear of magazine and shorten the ejector-bolt-stop.

This sort of rear bridge (M70 .270 WCF to .338 WinMag action) ...



... works as well as this sort of rear bridge (M70 .375 H&H to .458 WinMag) ...



... at ejecting 3.6" COL , unfired cartridges from a 3.6" mag box with proper fit of ejector-bolt-stop.

So why bother lengthening magazine and refitting ejector on the Super Grade .458 WinMag
to turn it into a .458 WM+ for 3.6" COL?
The .30-06 actions will do that by adding a bolt face job to the conversion,
and they are easier to come by and available in stainless.

No need to re-bore my M70 Classic stainless .375 WbyMag.
No need to muck with my M70 Super Grade .458 WinMag nor Alaskan .375 H&H.
Not even any need to rebarrel the M70 Extreme Weather .338 WinMag.

Have spare .30-06 will convert to .458 WM+.

Another advantage to the longer rear bridge, besides just looking beefier and stronger:
Less rain can get into the action.

The ones from FN/SC/Portugal have a longer extractor and only two screws in one-piece bottom,
and a funky new trigger.
Oh well, nothing is ever perfect.
