I have a .22 LR cal. Savage Sporter in just excellent condition that I've been shooting a lot lately. It is the exact make and model (although not the same one) that I fired when I was about 5 years old, some 78 years ago. I bought it on Gunbroker about 15 years ago and never shot it much till this year. The serial # is 1155xx. Do any of you guys know how to look up the DOM of this fine old gun? Thanks for any help....
