Yes short, long or long rifle.
Needs to be examined by a good gunsmith
Yes, the H&R model 949 (Forty Niner) is made to shoot .22 short, long, and long rifle. The barrel should indicate this. It should appear as: .22 cal, S, L, LR
Yes. You should clean the chamber if you shoot a lot of shorts- you can get a buildup of carbon in the chamber that may make chambering a long rifle cartridge difficult. Nothing special- just a brush and powder solvent.
Not recommended.
Any bolt action .22 rifle will shoot .22 shorts and will likely feed them acceptably. Pump action rifles usually will work acceptably. In the early/middle 20th century, Browning/Remington manufactured a model of the .22 Browning Automatic (Remington Mod 24, if memory serves) which was chambered for .22 short only.
yes it only takes 22 rim fire shorts
Pretty sure all .22's can shot .22 shorts, although if its a semi auto they usually dont have enough power to cycle the bolt.
Because the 989 is a magazine fed rifle, the 22 short may not feed properly. In addition, if you fire many shorts in the rifle you run the risk of building up dirt that will attract moisture and cause corrosion. If the chamber gets corroded at the front it will not feed 22 long rifles well. If you must shoot sorts, clean the chamber well when you are done.
Not desgined to shoot the 22 WMR
It depends on what type of bullet you are shooting, whether it is .22 shorts or .22 longs, but on average 18 to 22. You can also purchase and install yourself a tube extender that can shoot up to 35.
The 550-1 is a semi auto .22 rifle made by Remington. It is unusual in that it can shoot shorts, longs, or long rifle cartridges. Value can range from $100-150, depending on condition.
You can't find them. What you can do is offer to buy my whole rifle which has a good bolt in it. I'll take a newer Marlin 981t as trade. tackleberry65@hotmail.com
