That ought to be a super fun plinker, I bet it's darn accurate too. New-old rifles are my favorite kind as well. 
That would be the Browning SA-22.Dont no the model# but i think browning had a model that loaded thru the stock.
Sorry guys! It was a Winchester Model 63. What tipped me off was remembering the way that you depressed a button past the forearm to load the round into the chamber. Found a picture last night on one of Winchester's web sites. The "other side" of the family has the rifle - but not the memories. I guess I'll have to hang onto those for a while.I remember my grandfather teaching me to shoot with a .22 that he had. It loaded by unscrewing something in the butt of the rifle, pulling the tube back, then loading the .22 Long Rifle bullets into the side of the wooden stock. After loading nine or ten of the rounds, you pushed the tube back in and screwed it in tight. Can't remember for the life of me the manufacturer make or model.
Anyone have any clues???:wallbash:
