I'm a south paw looking to put together a short action 6.5. I've narrowed it down to a 6.5-284 or 6.5 WSM. I wouldn't consider myself a long range hunter preferring 400 yds. or less. I've heard the 6.5 WSM is a bbrl. burner. Any suggestions? Montana Rifleman will soon have their relatively inexpensive action available in various LH configurations and offers chambered bbrls. in both calibers I mentioned. Is their product any good? Are they competent at building an accurate, square barreled action? If I could find one I would go for a short LH Rem. 700 but they're kinda hard to come by.
