Rem 700 30 nos build question

[SouthLoganCountyShooter]

Ok I have a 700 bdl magnum action. Rebarreled it to 30 nosler. Had to open up the lower a little to get it to feed from magazine.
Still having issues with feeding. Wanting to convert from bdl to box mag. Anyone know if box mag conversion for 300win will work?

Moved to correct area.

Use a center feed follower and mag box

Yep I would use the Wyatt's CFE-12 kit.
