TC Contender and rifling twist rate???
I called up a custom barrel maker yesterday (I won't mention who for now) to order a Contender carbine length barrel in 300-221. I specified a 1/8 twist, and was told that they did not offer that twist rate for the Contender because of the chance of overpressuring the frame if super-sonic loads were to be used.
Does anyone have any thought on that?
