The rifle listed right around $80 bucks in the early '70's. Funny, but the whop of that little slug against a big pasture grizzly is one thing that I remember too.
I did not have a .22 mag either, and when the ammo supply dried up, I wish that'd been what I'd gotten. My rifle has been retired for nearly 30 years, but back in business now.
Could never part with it as gift from my Dad.
