As you state, your Ruger 10/22 has a "Bull Barrel" while my 10/22 had just the regular sporter weight barrel. The biggest problem I had with the Ruger was that it changed point of impact with each shot. I used it a few times for Squirrel Hunting but never got one Squirrel with it, all misses. I traded this semi-auto for one of T/C semi-auto "Classic" which was better, but it too wasn't as accurate as my currently owned CZ 452 American Classic. At least the T/C .22 "Classic" Auto was ALL Steel construction & the barrel was screwed into the action while the Ruger is just held in place by two bolts. I know the Ruger has a plastic rotary magazine, and if you are happy with your Ruger then I certainly would keep & use it for your Hunting.
