I built a 22-250 50 years ago on a 6.5 Arisaka, Douglas bbl and Herters stock. Wore a K-10 and Timney trigger. 250 bucks all done. Shot one hole groups and killed 100s of chucks and crows.
Better lock time than an 03, way more gasproof than 03 or Mauser, far stronger than any military action.

Silly to consider today but back then --------
