Depends on your mechanical ability and willingness. I started into some savage re-barrelings a few years ago and with patience and some good tools it was easy to do.
Some barrel mfrs now make "remage" barrels with the savage nut but in the Remmy style so you can do the barrel swap yourself.
Get that, a pair of go/no-go gauges, and some barrel tools (I even made one, my barrel clamp out of oak boards-pieces and clamps) and you can do it.
What I don't know is whether the fatter 6Arc/grendel case will load from a basically 223-spaced mag arrangement (whether internal or dbm).
Plus you will need a gunsmith to turn out your bolt head to enlarge it to 0.442; Remmy's have 1-piece bolts right? Or is there a 6PPC or 7.62x39 remmy bolt?
