I'm seriously thinking about rebarreling an XS7 to the 358 Win. Has anyone done this, and, if so, what length did you choose? My initial thought was to go short, ~20", but I do like the balance of the rifle now and am wondering if a longer barrel might be better to retain that balance. I'm more interested in retaining the feel than crawling through the brambles. I will keep the synthetic stock, so realistically, would the balance change drastically with a short barrel?
