Hmm.. I don’t believe 1:9 was ever offered in 22-250 Charlie. It was the standard for 223, that is correct. But never in 22-250, that I’ve ever even heard. Remember that barrel twist & velocity share a bond. Less twist is required for the same length bullet at 3800fps than is required 2800fps. And 22-250 being a laser beam, that was Savage’s rationale on the matter.
