My vanguard s2 in 270 win. has 1700 rds shot through its factory barrel. Its had good days ( 8 point whitetail 310 yards) and because it has a throat of cheap hooker im getting 140gr SGK to 3050 fps with h4350. Thus it turnned out to be quite the barrel burner. I need advice on rebarreling. Douglas will work on metric threads, square the action and install XX ss barrel for under $600. Also Im considering 6.5 284 for 140gr performance and bullet selection. Anyone have better option on smithing / barrels? And as far as ACCURACY is concerned am I on the right track on 270 win. vs 6.5 284?
