No, at least not on the original production guns (1892 - 1941).
No
The chambering will be stamped right into the barrel.Since it's a 94, it will probably be stamped 30 WCF (Winchester Center Fire) which today is called 30-30 Winchester
Yes
Completely depends on the ammunition you use. The long barrel tends to be just a little slower with most .22 ammunition but they are a highly accurate rifle with most ammo....
1892 Winchester caliber .44-40 carbine with a standard 20-inch barrel
The rifleman as seen on the old TV series used a Winchester model 1892 rifle,or a reproduction of that rifle.
22 Short, 22 Long, or 22 Long Rifle rimfire interchangeably.
Your Winchester model 1894 angle eject(AE) will accept any commercial made ammunition marked by caliber .45 colt.
It shoots .22 Winchester Automatic ammunition. It is obsolete and out of production but can still be found for sale by individuals on internet auction sites, etc. . It is NOT the same as currently produced 22 s,l &lr ammunition.
If your barrel is marked .300 Savage then you can shoot .300 Savage ammunition by any manufacturer. I do not know of a "300 Savage Winchester Magnum".
It should be marked either on the receiver or barrel Mine is marked .410 3" chamber, and it works extremely well with WInchester Super X ammo
