No. Two totally different cartridges, and it is HIGHLY unsafe to attempt it. No.
No. You wouldn't even be able to get the .303 to chamber in a .30-30 rifle. They're two very different cartridges, in no way interchangeable with each other, and this should not be attempted.
Yes, the Charles Russell 3030 Savage rifle is a lever-action rifle designed by Charles Newton for Savage Arms in the early 1900s. It was designed to shoot the .303 Savage cartridge.
yes there is a springfield .303 i have one from 1942 its a springfield rifle with a .303 british barrell
Assuming you mean a rifle such as the SMLE, the cartridge used in the .303 Enfield, also called .303 British. See the link below for information on this ammo. However, if you are not certain (some military surplus rifles were rebarreled into other calibers) have a gunsmith take a look at it.
The .303 British and .303 Savage are not the same. Only purchase the caliber that is printed on the barrel.
Depends on in which nation the rifle was built.
What is my 303 savage model 99 worth?
Original chambering was either 303 or 30/06. DO NOT SHOOT UNTIL EXAMINED BY A COMPETENT GUNSMITH AND GIVE A CLEAN BILL OF HEALTH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
