Gain twist on 300 win mag

[darthceadus]

I was looking for information on gain twist but came up empty. There is some posts about it that say it reduces pressure allowing you to run more powder. The posts were a couple years old. What do you guys think about it? I don't hear to many people using it, besides George from GAP. He definitely knows what he is doing so there must be something to it. If you guys have any info or links it would be appreciated.

i built a 6.5-284 with a gain twist and i didnt see any difference in anything. couldnt use any more powder and didnt get any change in speed.

I always thought gain twist sounded interesting until I started designing things. If you think about the fact that the bullet is accelerating in velocity from zero as it proceeds down the bore, it is also accelerating in RPM starting from zero. So gain twist is kinda redundant, as far as I can tell.
