i have a old 6.5 swedish m96 the rifleing is still crisp but as far as i stick out the 142 gr matchkings and still keep neck tension they will not touch the rifling is the throut burned out and can i salvage this by shortening the chamber and getting it re chambered and re threaded. or should i get the brand new m38 barrel i got installed. it prints about 1 inch or so 5 shot with hand loads
