Yes.The Winchester model 1876 rifle was the only rifle made by Winchester that was chambered for the 45-60WCF(winchester center fire).
The M4 is capable of automatic fire, the AR 15 is not
no
There is no such rifle, the Winchester Model 88 is a highly collectible lever action center fire rifle available in .243, .284, .308, and .358.
the 32 Winchester special lever action model 94 shoots a center fire, rimmed cartridge.
The difference is explained in the name. A rim fire rifle uses ammunition where the hammer strikes the rim of the bullet. In a center fire rifle, the hammer hits the the center of the bullet. Rim fire ammunition is usually small, like a .22, and center fire ammo is generally larger.
the ammunition would be the 25-20 Winchester center fire (25-20 WCF). ammunition is still manufactured by Winchester for this rifle.
The barrel should be stamped 30-30 winchester.
Winchester made one
It fires a 7.62x51mm NATO bullet, which is similar to a .308 Winchester.
Your Winchester model 9422 which was made in the the final year of production 1994 will bring between 350-500 dollars.
Your question is difficult to answer because there is no "20-20" Winchester. The model 1894 was the first rifle available in the new smokeless powder 30 WCF cartridge (Winchester Center Fire) aka "30-30". If this is actually your rifle it was manufactured in 1913.
