Older Rem 700 LA bolt question

[USMCSSGT]

My action is a 1966, has no antibind groove on the current "06 bolt.

Been thinking of building it up to 300Wm. Will a mag bolt that has the antibind goove fit into my older action? (meaning the lugs have the same outside dimensions)

Yes, I've used a modern production bolt in an old Model 721 action. Should work in yours.

Thanks!
