    Good or bad, what's your experience?
    I'll be using it for .357 Magnum mainly...

    I use 2,5,7, & 9. They meter well, rarely any leftover in casings, clean up easily and have provided me with a lot of really tight groups. I use primarily Accurate powders in my pistol loads.

    AA7 is about like Unique in 357, but cleaner and meters much, much better. I use it for an 1100fps load with 158gr in a 4" barrel, which is all I want in a K-frame. Where it really shines is hot 45acp loads.

    I've loaded .357 Rem. mag. with AA#7 for plated bullets and it works well. I will most likely phase out #7, #5 will serve this purpose and it works very good for 45acp, AA#9 and Blue Dot are my preferred powders for jacketed bullets. The barrel lengths of my .357's are 2 3/4 and 4"
    Please tell us more, what gun/s and barrel length? What kind of bullets, and for what purpose ? AA#7 may be ideal ?

    Love #7 for 9mm. Use #2 in 38 Spl loads.

    One of my favorites

    Great for just about everything. Meters very well, fills in where faster powders can't. Use it in hotter auto rounds e.g., .357 Sig, .40, 10mm, and .45s or for filling magnum pistol cases to sane pressures without needing magnum primers. I have been happily using a ton of it for all but the lightest small bore target loads or heaviest big-bore bear busters.

    Thanks, that's all I needed to know...
    BTW, the barrel length is 5'' and the bullets will be 158gr SWC.

    Are these bullets copper jacketed or are they LSWC ?

    Some are jacketed, some are lead. Why is that important?
    I'm not going to use it for powerful loads, just for target shooting.

    For lead target loads I prefer faster powders like AA#2 (I use Bullseye) it will burn completely at lower velocities, w/ AA#7 you may need to push lead bullets faster than you want.

    Sorry for the short post this morning,
    Lead is slipperier than copper and it takes less force to push it through the cylinder mouth and barrel, this results in less start pressure for the powder, and slower powders have trouble burning completely with lighter charge weights. If you want only one do-all AA powder for .357 I would go with AA#5.
