Wanting to rebar real 2 savages

[acj7382]

I've got a Savage Hog Hunter and want a 22 inch barrel with 5 r Rifling in 308. Same barrel contour. Have an older model 16 weather warrior in 300 wsm and want to convert it to a 300 win mag long action. Looking for a good barrel maker for the first in 308 that doesn't cost arm and leg and wondering if it's possible to change the short mag to a standard and what it would require as far as magazine and bolt.
