That may be possible. I have a blind mag centerfeed rifle in .22-250 and is using the standard .308 housing (says "STD Short" on the side of the housing) and it feeds fairly well. I do have the occasional round pop out and jam the tip of the bullet into the breech of the barrel below the chamber, but it works fine 90% of the time. Not sure if it could be sorted out with a little more tweaking or not, but at this point I haven't bothered to mess with it.
