i have been shooting colibris ammo through one of my 22 for a while and have never had a problem.(glenfield model 10 single shot bolt) and i have been wanting to shoot it out of my marlin model 60,but i am scared of messing up the barrel. my glenfield was a beater and i didn't care what happened to it. saturday i got rid of the glenfield at a gunshow(which i now regret) and i have been wanting to do some backyard rabbit and squirrel hunting.is it safe to do it through my marlin?
