An old post on the Rimfire Central web site stated that a 10 round magazine for the Weatherby XXII made in Italy could be altered by filing down" something" that would allow the magazine to be useable in the Beretta Olympia .22 caliber rifle. No pictures were shown and the description was not given with any details.

If anyone has done this alteration, and can describe in detail how to do it give me the details. I would like an extra magazine for the Olympia.
