Who needs a bench gun when they can shoot a highpower rifle?
Point is, you don't know what you are talking about on this one. You don't twist for a caliber... you twist for the bullet and velocity you are chasing...
And I'm not flaming ya either, its pretty much exactly what the benchresters do. You match the bullet length mostly, to the MV, to get your twist. They don't over stabilize at all because they shoot very short range shots, others like us tend to overdo it a hair because where BR stops mostly is whwere we start mostly and head on towards 1000 yards there so stability is key.
Where an 8 twist 30 cal might be ignorant in a 300 wtby driving 150 grain bullets( some folks believe in light bullets for some reason) the same twist isn't with a slow 240 grain 30 cal. And vice versa the slow twist for trhe 300 wtby, would leave the 240 slow 30 cal almost tumbling as it left the barrel.
