Purchased a Springfield Waypoint in 6.5 PRC earlier this year and had the EXACT same issues with brass scarring and ejection that OP described. Moreover when cycling the action I had a round get stuck unfired in the chamber.
I sent it in and they said it was a headspacing issue. Customer Service seemed solid.
The brass scarring was from the 300 WSM magazine they provide with the gun. Dremel polished the feeding edges of the mag myself which mostly eliminated that issue. However, the move is to reach out to
@HawkinsPrecision for one of their Hunter DBM’s. Nick is very helpful.
To date, the rifle is extraordinarily accurate and ejects fairly consistently with shot brass when running the bolt with authority.
However, given the above and the fact that even my friend’s Ruger American cycles better, I can’t wholeheartedly recommend the Waypoint for someone in the $2k range. I would look to the new carbon fiber lines from Fierce or Bergara released this year. Looking back, I should’ve just built the dang thing myself with the AG Composite Alpine Hunter stock they use.
