Aa3100?

[shorttrac]

Just picked up four pounds of this discontinued powder. Burn rate seems around 4831 ish which suits my needs, but curious if anyone has had any luck with this in .30-06 or .257 Roberts?

It is on a slow side for .30-06, however excellent for ultra magnum family.

I used it with great results in a 280. It's a bit slow burning for optimum velocity in both 257 +P and 30-06, but it will work
