It is stamped on the barrel and would be either .30-30 or .32 Winchester special as the two most popular calibers. Very early rifle might be marked 30W or 30Win.
Actually, there are a lot more possibilities than those two. This model was manufactured from 1894 until 2006 and has been chambered for everything from .22 to 38-55, including some like the .357 magnum that are usually considered revolver cartridges.
Add 44 WCF to that list.
Your rifle was manufactured by Winchester as their model 121. The spent shell is removed from the chamber by action of the right and left extractors and is then bounced out by bumping agains the ejector. Look for problems there. Parts are available from gunpartscorp.com.
The "parent" cartridge was the .250 Savage, necked down to .22 caliber.
The model 6 Winchester wich came from the model 1890 should be actually a short, long, and long rifle .22 catridge. Which is quite intelegent design it will chamer all rounds even if you mix them up in the tube. {and if you are woundering what a .22 long, well it is the .22 long rifle shell but a .22 short bullet. the regular .22 lr. has a longer bullet.
Winchester stopped the regular production of 20 gauge in 1963 and the 20 gauge magnum shell wasn't introduced for several years later.
3 shot (1 in chamber & 2 in the tube)
2 3/4" or 3" shells only
I have a Winchester 16ga model 1400 I got it a few days ago I cleaned it and went out to shoot it but it does not want to eject the empty shell, what could be the problem, anybody?
The chambering will be stamped into the barrel next to or under the Winchester name.Model 1890's all had .22 caliber barrels, but they could be chambered in short, long, and long rifle (LR).You might even find one in .22 WRF (The fore runner of .22 magnum.)If there is no chambering stamped in the barrel, or it only says .22, it's chambered for the .22 short.The reason being that it was made before .22 longs and LRs were commercially available.
You need the services of a gunsmith.
50-1000 USD depending on specifics.
it might be for the Krag rifle, cal. 30/40..... not 30/06
Yes as long as you get one made for the Winchester model 1300 and chambered for the same length of shotgun shell that the receiver is chambered for.
