Bullet stabilization:

a longer barrel with a slower twist can stabilize a bullet that it otherwise shouldn't be able to.

you cannot over stabilize a bullet.

the weight of a bullet isn't the key part about twist, its the length of the projectile. Longer projectiles (heavier) stabilize better with faster twist.


so: a 55 gr (because of the projectile length) can be sufficiently stabilized by a 1/9 twist. A 77 gr can also be stabilized by a 1/9, but you can get better LONGER RANGE stabilization and accuracy using a 1/8 or 1/7 twist. A 55 gr can also benefit by a faster twist.

Good points, Belly. I was wanting to touch on bearing surface, in my ramblings yesterday, but I knew that would start to get me in over my head pretty fast. I feel like I have a pretty good handle on the theory, but many of you guys have far more actual knowledge/experience.

Best read I've seen for understanding the topic (and myths) of bullet stabilization.

http://anarchangel.blogspot.com/2007...mythology.html

In short, the LENGTH of a bullet (and longer = heavier in general) the more air can disturb the bullet. Higher rotational stability is needed to prevent the disturbance. A faster twist barrel provides the necessary rotation.

Think of how much rotation a really short top may need to remain upright if you blow air on it, vs how much rotation would be needed to keep a much taller top stable.

Barrel length affects stabilization only by virtue of loss of velocity affecting rotation speed.

Looking forward to reading this.when I can do it on something larger than my phone.

Hey Stoner, how's the job hunt going?

Got a few apps in currently. That's about it.

Ugh, i feel really crappy this morning. Headache, tired, stomach is kinda messy... I sort of feel hung over. I didn't drink last night.

Awesome. Good luck!

Hahaha great story BC. I laugh because I've done this too...

Cat's rules:

1. Never puke on a hard floor if carpet is nearby.
2. Puking is required in more than one room.
3. Cat must immediately return to the food bowl from whence it just puked up and re-prime the puke pump.
