I have heard of those devices, but no experience. Bullets do jump when they leave the muzzle as they are forced to rotate about their geometric center in the barrel, but immediately change to rotate about their center of gravity when they exit. There is something to it. Harold Vaughn may have addressed those ideas in his book, Rifle Accuracy Facts. I have read it, but do not own a copy. It has a lot of interesting ideas that you do not hear too much about. I recall that one of this theories was that fast twist barrels can actually twist the jacket and outer lead portion around the center lead portion. Some bullets explode before they get to the target as a result, and it kind of becomes obvious there is a problem. His theory, I recall was that bullets which twist but don't explode can become unbalanced and simply cause accuracy problems. I know that people like Bryan Litz like to push high spin as the solution to everything, but there are issues to consider. There is a reason 100 yard benchrest guys choose the slowest possible twist.

Is anyone shooting this combination out of a 300 win mag. I have a 10 twist. At 200 yards i found they grouped like crap but out at 500 yards they grouped very well. Is a 10 twist fast enough to stabilize them at shorter distances.
Answer to your question is yes the 1in10 twist is more than capable of stabilizing the 215gr Berger pill.
There are many factor's as to why your group's are tighter at 500yard's over 200 yard's. If you need to tweak your load a little why not tell us a bit more, such as barrel length , component's being used, powder charge's , primer's , etc....... How extensive has your load development been ? What's your shooting condition's ?
