87 VMAX blows up

[FW Conch]

Yes, stability was my concern. I have 748 and CFE223. Should get to try it out next week or so.

Thanks...Jim :-)

Texas 10,
There really isn't an answer to your question, other than "it depends", but here is a little discussion about it.
There isn't such a thing as "over-stabilization", there can be an induced wobble if you spin super-fast, but below destruction RPM; IF the bullet ins't perfectly concentric. But there is no way to know if the ballance of the bullet would be X, nor if they would all have that same amount. So you really can't compensate for it, nor would any but the most advanced tests be able to pick it out when shooting.

As for "The sweet spot" for RPM, it is better to not think of hitting a number like 250,000 RPM, rather a spin ratio as can be found on the JBM site. The reason why slower twists work well, and what many don't think about is how everything is relative. A bullet needs a stabilizing spin based upon it's length, AND forward velocity. The spin is important to the velocity, thus the better description of a stability ratio.
As a bullet travels, the velocity decay happens relatively quickly. The bullets rotational decay happens VERY slowly. So as a bullet travels a great distance, it's stability factor actually increases; because relative to it's velocity, the RPM has increased.
