A 4.4 spacing will be a centerfeed. Better for you cause it’ll be easier to find what you need.

So you need a centerfeed short action blind magazine and follower.

Next is caliber? What is it or what will it be? That’ll determine which mag box it needs to be(204/223, 243/308, or WSM?).

Then I would post a want ad in our classifieds for exactly what you need and maybe someone has one lying around. Don’t use the general term of “110” cause it throws everything off, although the newer 110 short actions take the same magazines. Just use centerfeed short action for “?” Caliber..
