Only what it is chambered for.
.22 mag and .22 LR are not the same. So, no.
The answer is yes...and no There are several models of Weatherby rifles. Different models are avail. in a plethora of calibers. Here is an example: If you have a Weatherby Mark V chambered for 7mm Weatherby Mag YOU CANNOT shoot 7MM Remington Mag ammo. Dont look at the manufacturer of the ammo, look at the caliber and do not interchange. Weatherby has several "propriatary" calibers, wby 7mm, wby 270, wby 257, wby 460, and others. Look on the barrel for the caliber stamp. If your rifle is chambered in one of these "weatherby" calibers, you must shoot either Wby ammo, or reload. If your rifle is chambered in a standard caliber (270 win, 30.06, 243, 7mm, 257, etc,etc, you can shoot any munufacturers ammo that is in that caliber.

Which caliber?
Rifle chambered in one of the cartridges named Winchester Magnum- such as the .300 Winchester Magnum- or .300 Win mag for short.
No, the 300 ultra mag cartidge is not interchangeable with the 300 win mag.
3500.00
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".
You need to know the make, grade and model. 270 mag rifle could be anything
Yes,Remington designed the round, and it can be fired in any good quality gun chambered for 22-250. Just as 300 Winchester Magnum was designed by Win, but any make of 300 Win Mag ammo can be fired in any good firearm designed for 300 Win Mag.
100-450
300 Win Mag would be one.
No
