It's a warning to the user that the only compatible ammunition for that rifle is the .22 Winchester Magnum Rimfire (22 WMRF), and other types of .22 ammunition are NOT compatible.
Winchester Magnum rim fire
Armalite Rifle, Model 15. It does not mean assault rifle. Note that other manufacturers refer to their ARs with different designations; only Colt holds the rights to the name "AR-15".
22 long rifle only
the only rifle produced in cal 32-40 was the model 1893,either carbine or rifle,please check the model number again.
The rifle will shoot .22lr .22 short, and .22 long. Only .22lr will cycle the action and load the next round. .22 Short and long will function as bolt action only.
I can only assume that you are speaking of winchester,s model 1890 .22cal pump rifle?If that is the case then your rifle was made in the last month of 1923.
If you mean the US Rifle, Caliber 30, Model of 1917, manufactured by Remington, these were produced only in 1917-1918.
What is a Winchester Model B? With a serial number that high, I think it could only be a Model 12 shotgun or a Model 94 rifle.
Only the factory knows and they are not telling.
The only Winchester chambered in 45-60 was the Winchester model 1876 rifle.
It is not possible for you to have a "Model 97" in 30-06. The Winchester Model 97 is a shotgun, and was made in 12-gauge of 16-gauge. The only Winchester models that were or are chambered for the 30-06 rifle cartridge are the Model 54 bolt-action rifle, and the Model 70 bolt-action rifle series.
The Mossberg 46B(b) was only made in 1947-1949, when the model number changed. Excellent target rifle.
