hi-tech AA#7 equiv. in 357 sig?

[rufracer]

anyone messin with this combo?

[mike in co]

no, while it might be listed in aa , i think with the light bullets shot in a 357sig you will get poor burn characteristics, aa5 i think is a better match,

Are you talking about pr700?

Bigdog, It's 9mm NATO powder. It is 10% faster than AA#7. I use it in 357mag, 38 special, 40s&w, 44 special, and 44mag. I wish I could help you rufracer, but I don't load 357 sig.

I use this powder in 40s&w, 9mm, 38special +p, and 357 mag. burns well in all of them. I plan to use boolits from a lee 124gr fp tl mold, water dropped. Its also a 6" barrel which should help it burn off. Ill use AA#7 data and go from there.

Thanks all.

I shoot LilGun and a canister lot of AA #9 in my 357 SIG and the velocity and accuracy with jacketed bullets is outstanding. Haven tried cast yet, as I have a heavy spring in it for business loads.

I use it in .357 Magnum; gonna try it in .30 Carbine for my Blackhawk when the weather warms up. I use BlueDot data (cautiously.) I wish I had bought a lot more of it. HTH.

so far ive loaded up to 11.5gr of 9mm nato in the 357 sig without preasure signs using cci small pistol. I do in fact have some unburnt powder in the barrel with this load, but I am producing 1600fps with a 124gr cb out of a 6" barrel.[smilie=1:

ok, so there is some bolt imprint on the primers
