Would be nice, but not holding my breath; it's all about the bottom line.
I do see some movement to multiple twist rate offerings in "varmint" calibers, e.g.: C-Z and Savage in .223, Savage in .223 and .22-250 and a selection in some chamberings through their Custom Shop.
Also: Why do factories still run the .22-250 (and .220 Swift) with 14-twist barrels? Even a 12 would do better at stabilizing some of the longer/heavier bullet offerings. I'm wanting a Swift with a 1:12 to run the 53 V-Max, but will have to go with a custom or re-barrel to get it.
