If it has a box magazine, it will only handle .22LR, and detachable box magazines are famous for developing feeding problems if they are dropped or handled roughly. It is also not unusual to hear about detachable magazines being lost or misplaced.
If it has a tubular magazine, most often that means it will cycle any .22 RF ammunition with the exception of the magnums. - And it will do so with utter reliability. An additional benefit is that there is no box magazine hanging down, getting in the way of the balance point on the rifle. They are
much nicer to carry and handle.
My Marlin XT-22 TR bolt action with a tubular magazine shoots Long rifle, Longs, Shorts, and several other varieties interchangeably. I find that the .22 Shorts are especially useful. Mine holds 25 of them.
The thing is a tack-driver. Shooting .22LR high velocity rounds, I like to throw an old golf ball about 25 feet in front of me, and when they are shot they obligingly bounce and roll downrange. They usually have get 75 yards or so away before it might take more than one shot to hit them again. At 100 yards, it really starts to be a challenge. You have to hold over quite a bit.
That kind of shooting is very instructive. - More so in general than shooting at paper because the target is small, and the range varies at random from shot to shot. This assumes of course that you have already shot at paper in order to get the rifle sighted-in properly.
A good rule of thumb on scopes for 22's is to spend at least as much on the scope as you did on the rifle. Cheap .22 scopes are a very unwise investment.
Use the open sights until you can afford something really good. - Shooting with open sights is instructive in its own right, and lots of fun too.
