I have an old Mossberg 640k .22 mag that shoots great. Trigger pull was awful though, I had a gunsmith fix that. You can pick them up at very reasonable prices if you watch the used gun racks. I also have a couple Ruger single six convertibles. I have one set up for LR and another for 22 mag. The mag is way too loud to shoot out of the 45/8 barrel without muffs, but it shoots very well. The .22mag will sure knock a fox squirrel out of a tree!
