carbon on outside of neck

[josh shrum]

FWIW- this is a 5 year old thread. At least one poster is no longer with us, unlikely he will respond should someone direct inquiries his way. But still a good topic.

Good catch, lol.

You must not be aware of the Sine Neck Optimization Theory (SNOT). The theory is that the case neck "sine wave", when spun at the same rotational speed as the bullet at muzzle exit, will produce the same frequency as the barrel harmonic vibration. If it does not, the load is clearly not optimized. The cases are really a pain to spin that fast, but the results are worth it. When the case neck sine wave and barrel harmonics are in tune, a area of 1.5-2 meters around the muzzle becomes fully in sync with the universal constant and all bullets will go through the same hole, regardless of conditions.

What is the frequency?

What is the frequency?

Only Kenneth knows.

Only Kenneth knows.

Only applies to Rem brass???

Only Kenneth knows.

Eew,and they beat him to find out!

please, nobody talk about powder residue forming a "sine wave".

Hey, I like my sine-wave.
