Fifteen or so years ago, after my informal but repeated testing in phone books with both of those revolvers, no .22 LR ammo from the 317, including Stingers, even came close to the penetration of Win. Supreme 34 gr. WMR HP's from the 351. Expansion is a separate matter and a little info on the internet about expansion can be found..

Today, however, I don't have a 317, an indoor place to do repeated, measured penetration testing or current-day ammo such as the hot Aguila Super Magnum .22 LR or 36 gr. Maxi Mag ammo. Nor have I found any actual testing of those two revolvers pitted against each other on the internet.
