I have a 4X Simmons 22 Mag scope sitting around the house and I wonder if those scopes are only for rimfire rifles or not. If I could, I would like to mount it on a Thompson Contender carbine in 30 M1 Carbine but I'm not sure if even a light recoiling rifle round like the 30 M1 will tear up the scope or not. Has anyone ever mounted one of these 22 mag scopes on a centerfire rifle with any success?
