i have four ruger carbines in diferent configurations.i use them here in the adirondacks for deer hunting,very effective on distances to 100 yds.set up with a electronic red-dot type sight or a small compact low power scope these make an excellent deer rifle.the older carbines have become fairly expensive,i have no experience with the new auto-loader.
if you keep them clean and use a good load they will serve you well.i use a load of 22 grns 2400 with a 240 grn xtp feeds and functions great.very effective on game.
another ruger 44 you might want to consider is the 77/44 bolt action no need to worry about jamming,and you can shoot any load you want from it without worrying about them feeding.they use a rotary clip similar to the 10/22 i have one of these as well real accurate little bugger.my 11 yr old son likes to shoot this one,i expect he will prob use it to kill his first buck as soon i dad lets him.lol good luck,shawn
