Loads for .300AAC Supersonic out of an AR15

[Navybowhunter]

Hello all,

Looking for any load data on the .300AAC in the supersonic range that you are shooting out of an AR15 platform?

Bullet:
Brass:
Powder:
Primer:
COAL:
Did you taper crimp?

I have some 130 gr, Barnes TTSX that should be here today. I will try some Accurate 5744 powder (all I can get for now), here is what I will be trying:

Bullet: Barnes 130 gr TTSX
Brass: Remington once fired .300 AAC brass
Powder: Accurate 5744 18.5 grains (1940 FPS)
Primer: CCI BR4 primer
COAL: 2.065
Slight Taper Crimp

This is the load from Accurate, but looking for other options.

Signing up at the above forum will net you so much more info than trying to get info on it here. There is also a 20 page thread over at ARFCOM dedicated to the .300BLK in which you might find some useful info.
