I just put a Shaw 300 WM barrel on a 110 in .270. This rifle originally had a tupperware stock. The barrel channel was a little tight, just enough so that the front action screw wouldn't reach. I didn't try to fit the barrel to the factory stock as I am using a new stock. Just letting you know the Shaw magnum barrel in the tupperware stock will be a little tight, but nothing that can't be resolved by following the good advice above.
