140 VLD, H1000, BR2 primers, ADG brass. Just under 3100fps. Lots of room for more speed, but it shoots teeny tiny groups out to 900yds so that's good enough. Sub 7lb rifle so hunting distances will be limited to 600 yds. I would be more likely to follow a break in process on a factory barrel then a custom barrel, more tooling marks to get rid of.
