I'd rather see them offer a 1:8" twist 223 and 22-250, or, figure a way to have their SA magazine accept a loaded round of 2.95". How about an action designed around the .473 or .378 case head, IE much smaller diameter and much lighter.
Shhhh, that's my NEXT push for Winchester I have been pushing QT's awhile for factory rifles/ammo.
223, 22-250 AND 243 QUICK TWISTED (QT)in 1 in 8" has no downsides and ALOT of upsides.
No doubt would give shooters/hunters ALOT better options IMHO as I personally would not shoot anything BUT QT barrels given a choice.
