I know I've a Mauser action that was originally a J.C. Higgins Model 50 in .270 (and no, I didn't shoot the donor, but I was tempted!). The plan is a 9.3 x 62, but I keep thinking 6.5 x 55, or possibly 6.5-06 to take full advantage of the action length. Then I think, no, build the 9.3 x 62 and just buy a 6.5 Creedmoor Ruger American. Quoting Mule Deer, "One into two is typical Rifle Loony math."
