3) Friction is what caused the failures not rotational forces.
4) Bullet length all else the same determines twist rate not velocity.
5) If your gyroscopic stability is 1.5 it doesn't matter what velocity your shooting because a 1.5 GS means the bullet is stable.

6) The only time twist rate comes into play is guys with a GS of 1.2 shooting 1000 yards and maximum loads in a very long barreled 308..
This is absolute lunacy.
1) Maybe they do use them, but it IS NOT because of jacket uniformity. They would use them because of jacket damage in high heat, rapid fire situations Call Berger and ask them that, or better yet read that it isn't true in their FAQ.

None of this has anything to do with your false claims of G forces by the way.
2) That is also not true, but the WHY they would switch is perfectly reasonable. Again this is a deflection from your G force claims, and if they were killed by G forces, they wouldn't stay with these bullets as you claim. So which is it? You can't have both sides of the argument.
3) Friction is what damages the jacket, on that we both have always agreed. Once that bullet is out of the barrel, is where, in an attempt to keep this nonsense relative to the OP, in a high RPM situation, will then destroy the bullet. NOT the G forces.
4) I'm not sure what this is supposed to mean. I agree that bullet length is what you should consider to choose a twist rate. HOWEVER, ignoring velocity simply shows you don't understand what you are talking about. So here is your formula, AGAIN: MV * 720 / Twist = RPM.
5) Again, Velocity is CRITICAL to your stability factor, as it DIRECTLY affects the RPM. The RPM is in fact what gives you stability. Look at the formula, again, and do the math. MV = Muzzle Velocity. Without a velocity, there is zero RPM. Only a useless twist rate, and a cartridge in a chamber that you can't fire.
6) Again false. Why did the original 6mm Remington Fail? Because it had a slow twist to ensure that no varmint bullets would be destroyed. Thus it could not handle anything heavy enough to hunt game with, where the 243 had a twist that generally worked with several bullets.
Or more recently look at the 223 WSSM cartridge. If your claim of velocity not mattering or G forces caused the damage, then they would have used a 9-twist. Why didn't they? Because the velocity possible in that cartridge would impose an RPM that would destroy anything remotely useful for varmint hunting.
