This question would be better directed to a qualified gunsmith.The .22 magnum round is operating at a higher pressure then the regular .22 long rifle cartridge.He would be better able to know if the Winchester model 72A could with stand the higher pressure involved with this rechambering.
No, it is/was not.
yes.The Winchester model 9422M was chambered in .22WMR.
Only if it is chambered for it. If in doubt, go to a gunsmith.
The letter M after the model number 9422 indicates that your Winchester lever action rifle is chambered for the 22WMR(Winchester Magnum Rimfire) cartridge.
Yes, Winchester produced a lever-action rifle chambered for the .22 Magnum cartridge, known as the Winchester Model 9422M. This rifle was part of the Model 9422 series, which was designed for .22 LR, .22 Short, and .22 Magnum ammunition. The Model 9422M was well-regarded for its reliability and versatility, making it a popular choice among shooters. Production of the Model 9422 series ceased in the early 2000s, but it remains a sought-after firearm among collectors and enthusiasts.
Winchester stopped the regular production of 20 gauge in 1963 and the 20 gauge magnum shell wasn't introduced for several years later.
The Marlin model 1894, chambered in .44mag, will accept all factory .44 magnum ammunition. I recommend jacketed or semi-jacketed ammo to prevent lead from fouling the barrel. Other than that, you're good with any "off the shelf" .44 magnum ammunition you choose.
That rifle was made between 1892 and 1932. it could have been any time between this. Check Winchester Serial # for precise date on Web site for Winchester
The winchester model 670,and magnum models were made from 1967-1973.
There was no 300 Winchester Magnum cartridge in 1939. A 1939 Model 70 would be marked "300 Mag"...and it will be chambered for the 300 H&H Magnum cartridge. There was no other 30 Magnum cartridge in 1939 in the Model 70. The 300 Winchester magnum cartridge was introduced in 1963,...the last year the Pre'64 Model 70 was made. Your 1939 Model 70 may have had a later barrel swapped in to it. 300 Winchester and 300 Win Mag are the same cartridge.
Your Winchester model 70 bolt action rifle that is chambered in .300 Win Mag,has a twist rate of 1 in 10.
The only Winchester chambered in 45-60 was the Winchester model 1876 rifle.
