Thanks Rothhammer.

I think that "Pro-Mag" may work. I hope so. I intend to cut it down to a 5 shot sporting magazine anyway, so having an original is not really necessary. The only thing on my 2 rifles that are original are the actions and bolts anyway.
New wood, hardware and barrels as well as sights, so a new magazine should not be a concern either.
