well if you think that you might as well go ahead and quit then.

I think it's a combination of both, adequate spin to keep it on trajectory but not so much that the down leg portion prevents it from coming in nose first, nose down toward target. Overspinning I think they want to remain level on trajectory and when they cut paper they appear to be keyholing to some extent.
I think using the slowest power possible with a heavy weight for example...is to try to accelerate the cast as gently as possible...if you can even equate or imagine anything in the barrel as being gentle. Bringing the cast up in speed slower as it engraves helps prevent skidding that might widen the land engraving and potientially allowing gassing.
I think our PC coatings not only provide lubrication but also allow us to shoot a softer cast than we could shoot if we were greasing...especially the plain base cast that might vaporize from an extremely hot powder and deposit Pb in compensators or silencers.

Rcmaveric I suspect your onto something sir.
Was reading about that in the Lee book I bought yesterday Waco recommended. But your boolit has to be pushed to a specific velocity to obtain RPMs so I think it is hand in hand? So if two boolits pushed with two different powders at the the same speed would create the same RPM...would they not?
rpm is just the barrel spinning the bullet.
1-10 is 1-10 all the way to the paper.
I get instability with a 1-7 if I go too slow.
