My dad asks me if he got a "long action" 308, could he eventually rebarrel to a true long action cartridge.

Specifically, he wants to get the 110 Tactical in .308W w 24" bbl, shoot it out over a couple years, and then convert it to 300WM. Wondering if he could still mag feed the rounds or would hafta do single shot.

Would converting to 300PRC/300WM entail only: a) barrel swap, b) bolt face change, c) new stock or chassis to accept long action magazine ?

Does the action itself have a large enough feed port to accept 3.6" to 3.7" coal rounds? If not, could he or a smith just cut a larger port in the action?

I was looking at YouTube vids and the 110 Tac in 308 doesn't really look like a true long action. Tried to find specs but couldn't. Haven't called Savage yet.

Or would this all just be an exercise in frustration?
