one of the reasons winchester chose the combination they used instead of the 22 250 or a faster twist than 1/14, might be that the 22 250 wasn't around until 1937 and the bullets requiring a fast twist wouldn't show up for a long, long while. the 219 didn't show up 'til the late 30's either.
This isn’t true. Fact is Winchester turned down the Wotkyns Swift in 34. Based on Savage brass was the killer along with supposedly not thick enough web to give a 45 grain bullet 4000+ FPS.
