My dad and I were talking the other day, I let him know that I was going up into the mountains for a big Utah gathering for camping, fishing, and shooting. And I made the comment of "I just wish I had more guns to shoot while I was up there." He says, "you can take my old rifle." I had forgotten my dad had this thing. Apparently, it's a family heirloom that, from the looks of it, has not been shot since my dad was a kid in the 40's and 50's. It's a Remington Model 41, shoots .22 (short, long, and lr rounds). The stock is beautiful wood, the barrel is beccoming speckled with rust. I will do a complete cleaning on it before giving it back to him. If it's a family heirloom I want to keep it in perfect condition. I did a little checking, this thing was made between 1937 and 1939, that's incredible. I can't wait to take it shooting. Does anyone have one of these? I definitely don't want to make any mistakes with this. Is there any ammo I should stay away from?
