I'm rounding up a mob with torches and pitchforks. Anybody got a stout rope?
I still think 1961 is the safest bet. By then all the old slow twist barrels would've been used up and 1-10" barrels solidly in the pipeline.
Another question would be "why bother abandoning the old twist in the first place?" Does anybody here really feel handicapped by using a 1-14" barrel? Think about it.
Had the twist stayed at 1-14" I bet the bullet people would've put more effort into developing technologically advanced short/light bullets, and bingo, performance would've improved while retaining the original premise of the .250-3000 - lightning speed. But alas with few exceptions such wasn't to be.
In other words, in terms of "improving" the performance of the .250-3000, we're saddled with bullet technology of several generations ago, ie: "up the game with the good old cup-n-core by bumping up bullet weight." I often wondered why Nosler never offered an 80-87 grain Partition short enough to stabilize in the 1-14" twist.
