.358 Winchester is what I’d do.
That’s what I did.
Rebored a pitted .243 Pre-64 Fwt to 358 Win.
Sent it to JES in Oregon. $250 included return postage, took little over a week. More shipping time than turnaround time. JES guns usually shoot very well.
Cheaper than a new barrel and you don’t have to do anything with original stock.
