Savage magazine assembly swap.

[Buster95]

I have a Savage in 7mm rem mag blind mag centerfeed (magazine attached to the stock) I would like to know if I can change it for the same magazine but in 300 win mag, no modifications necessary? I'm interested in a build and I need a 300 win mag for this. I'm not sure if Savage use the same mag in their 7mm rem mag and 300 win mag rifles.

my savage 114 7mm rem mag is stamped on the side 7mm REM MAG and right under that is 338 WIN MAG, my buddies savage 111 in 300win mag is stamped 300 WIN MAG and the only caliber on the mag

Make sense the 300 win mag cartridge is longer than the 7mm rem mag.
