WSM in a lng action 110?

Will WSM cases fit and feed out of a regular stagger-feed 110?

Guess it depends on what "regular" is. In my long action 7MM Magnum magazine it was a no go but don't know about other size magazines.

They will, might need to lightly tweak the mag but usually is very easy to get them to feed correctly

Excellent thanks.

I have two 7mmWSM (one with bottom metal feeding from an AICS 300 win mag, on feeding from a magnum fixed internal mag)in a long action, with plenty of room to chase the lands with 180vlds. Both are staggard feed....
