I plan to do a re-barrel and wanted to know what all I need to do and which gun I have is best for the re-barrel effort.

I want a 6.5 grendel LW barrel and it says it is compatible with Savage 10, 110, 112 (and I bet a whole lot more).

Here are the guns I have and which of these will work for my conversion (using the same bolt) and will I need to replace the
mag feed with new follower, etc.?

Stevens 200 in .270 long action (I prefer to use this gun if it will work since I have another 270 with Timney).
Stevens 200 in 7mm-08 short action
Savage 16 weather warrior in 308

thanks in advance!
