You clearly have a lot of valuable knowledge that could greatly benefit lots of people....but you are more interested in showing how big of a prick you can be than actually add any real value to the discussion.... Swallow away buddy.....

PS and by the way,of course I am NOT "mistaken". I'm simply afforded the luxury,of not being forced to guess and that Fact very much troubles Window Lickers.

RR,
trying to keep it simple for Larry. The decay in rotational rate is going to result in a lower number, not higher.
So reckon we’ll never see any attempt at a real answer from him for the simple reason he is “mistaken.”
Got to head out, but will check in later.
ps for Larry on the other thread, 208’s are ok, 210’s are better, but .896 at 2950 bests both. google it.

No. Since velocity is decaying much faster than the bullet's rate of spin, the rotations per unit of distance traveled will actually increase as long as the bullet is in flight. If you've retained 97% of your rotational velocity but only 80% of your forward velocity, it cannot be any other way.

As well as a husband and father. Referring to him as "her" is a slap in the face, and you have done it to everyone in your few hours around here. It won't be long now, and you will be gone forever.

I'm getting back into this project, and need a barrel for my AR-308. It seems like splitting hairs with these twists though. I would like to use 140 grain bullets, and will reload. My 22" Lilja 1-10" SALAMI 7-08,will stabilize 162A-Max at low tide,when freezing,if only as a matter of fact...mainly because it is a fact. Throat,Twist and COAL determines what you can and can not shoot,as stability and housing same goes. A chambering can simply be no better than it's bullet and bullets matter wayyyyyyyyyyy more than head stamps. Now the only way bullets get better(BC increase),is to get longer,which requires more RPM and more COAL latitude. I'd not build a 7-08 slower than 9",if only because I've got 'em in all twist rates cited. I also wouldn't build a 7-08 on a '10 Krunchenticker,due COAL latitude. I'd go Kreedmire all the way,because it'll shoot softer,jump to lands less and will outperform same. Doubly so,when talking an idea as poor as slummin' .284" 140's in a Self Shucker. Hint............... I'm limited to the magazine capacity of the AR-308. Hopefully that helps. I don't want to use too big of a bullet so I don't have to give a up a lot of powder capacity in the case.

Changing COAL 1/10th of an inch(.100"),will not offer a "Magical" velocity advantage. What it will do,is keep the ogive closer to the throat,which typically increases raw Accuracy potential.
Long story short,you can scoot a 162 to 2600fps easily,in a 20" Krunchenticker 7-08,that is feeding from it's OEM mag confines. I'm an ASC Slut,because they are tough,reliable and the most generous in COAL latitude(2.825" COAL easily). 140's cannot begin to hang,a that COAL or any other.

Hint................ Got it now. I found those mags earlier, but never have heard of them. I have some Pmags right now, but think the plastic is a little thick. I think I'll try a few of the heavier bullets when I start testing. LaRue makes a good metal magazine, but I don't think it's worth $80.

Ran past someone who studies bullet performance among other things for the .mil.
Here is his answer: "Usually forward velocity slows before rotational. However, some bullets nearly stop spinning altogether when impacting."

So would that mean Chad is correct?

The who is correct is not as important as what is correct, but looks like expert's answer is different than all others thus far.
RR had the correct answer for the bullet in flight, but no one had the answer for what happens at impact, which appears to defy all of the theoretical jabbering. Doubtless our tax dollars are at work trying to find some way to predict what happens and how to improve the terminal effects as it seems inconsistent and unpredictable. Have to say that was a surprise.

Here is another example whwre I need to trap hogs, execute, and prop them up on a berm, and perform some "ballistics testing". Followed by autopsy.
