Magazine follower, bolt guide/feed rails, and God knows what else beyond the obvious new bolt and barrel, and the basic issue of the Remington long action versus their short action which was designed around the shorter cartridges like .243. Waaay better off just buying a .243 rifle IMO. "You can lead a man to logic, but you cannot make him think." Joe Harz "Always certain, often right." Keith McCafferty

So it's not that you can't .............................. but buying a new rifles in 243 would be a LOT cheaper.

Why wouldn't you sell it, if you don't like that round, and buy what you like! .243's are a dime a dozen! JMO I Learned a long time ago to Separate My Want's from My Needs!

Elinor took the clock to pieces to make a Victrola. And someone would take a 7mmRM apart to make a 243. While someone else would take a 243 apart to make a 7mmRM.
