I’ve read several posts/articles and videos on twist rate and the terminal side. All support a faster twist does better terminally. Bullets open up better and tend to track straighter and makes a better hole displacing and destroying more tissue. That and there was some discussion about I can’t recall if this is the proper term but radial KE, KE generated from the spin of the bulletsVery good discussion! Thanks to all who have contributed.
With my limited mind. I don't think there is such a condition as over stabilization. Can we spin the bullet too fast for conditions, absolutely we can but that does not mean that the bullet is over stabilized. It means that the bullet failed in its construction at the speeds we are pushing them.
We have in several instances reached the point of failure in the integrity of the bullets. Several factors contribute to this failure. Rough bores or throats, possible long barrels which heat the bullet more as well as air resistance heating them. Remember Hornady discovered that their plastic tips were heating up and failing at high speed and distance from air resistance.
When I wrote post #2 I was simply stating a fact. I was not stating that bullets do not fail because we are spinning them too fast. Simply put we need to optimize the spin rate/twist to match the bullet we select at the speed we intend to shoot it at.
As we push the envelope of the ballistics and projectiles we use we will find their weak points and find ways around them hence the monos. I am not convinced that the RPM rate causes the bullet to approach a distance target at a
drastically different attitude than a slower one that is only barely stabilized. I would need to see more proof than the video provided. I am not saying he is wrong just that I personally need more evidence. I think a bullet will always approach a distance target at a nose up attitude until it is unstable or falling straight down.
We are so used to thinking in terms of Revolutions per Minute and Feet per Second till I think we need to think in the same measurement of time. RPS and FPS. An example is a bullet at 3200 FPS with a 1/8 twist is 4848 RPS.
I also wonder if heat from air resistance is not playing a larger roll in bullet failure that we first thought. I suspect that the bullets are getting very hot at the speeds that are causing complete disintegration. Think space shuttle tiles. I have also been convinced that a fully stabilized bullet will have better terminal ballistics than a marginally stabilized one. Steve at Hammer Bullets backs that up. There is a difference in terminal ballistics and accuracy. Just because a slower twist will shoot more accurately does not mean that it will preform better terminally.
I admire those who test the limits not just talk about them. Thanks JE.
