Yes broke my heart as I looked down the barrel, it would have gone nicely with my BSA/lee speed sporters, same sights & engraved .
Yes it was a 6.5x53 so a rebore to 303 is in order, all the better for only being marked "nitro proofed" no caliber, just getting it to & back from the US is a major now days !
I have two rebored barrels stuck over there right now !
