starting out all over again, 10/22- you can always just load 1 in the mag and use it as a single, and proper dicipline will get you to the same place as a bolt single shot- the thing to remember is as you advance, that single 22 is going to be sold somewhere along the line , and you're not going to get much for it unless it's a target rifle or something- your 10/22, however, can stay with you forever and you can modify it as needed as you advance-
with the single load , the only thing you're missing is opening the bolt and re-cocking each shot-however, if you follow the dicipline-put in mag, pull bolt to rear and let go, then go into your sights and fire, then apply safety religiously, there's no need to buy a 22 twice unless you want to
the gun i learned on was a cooey 22 repeater( somebody elses)which was all about safety at the time, however there was also a 22 cooey that you had to pull the bolt rear back AFTER you'd chambered the round- this teaches you an extra step you'll never need again and possibly a bad habit that's going to cost you if you're shooting rabbits or something quick- keep it simple and you'll be fine- if you must have a 22 bolt, get a good used cooey
