Thanks for the site for the mag box. The 40 degree shoulder is what concerns me on the dasher. I know of a guy who has one(stagger feed), but he also rec. the 6X47 for a repeater when I built mine three years ago.
I am going with a defiance action and brux barrel. Stockys has those bobby hart LRT's on sale for $200. So I had to find something to build. I also am doing a little research for a caliber for my bench/f-class rifle.
I am starting to learn having 1/2 the year off(seven day schedule), I am spending more. I might have to get a different hobby or a second job.
