I'm just curious about what loads you guys use for AA#9. I don't have a chrony, so it's hard to verify my loads. I load everything using Win LP primers to 1.250" OAL. I'm more concerned with my 165gr load. For the gold dot, I'd really like to be between the 1300 and 1350fps mark.

Here's what I've got so far as well as my estimated velocity from my Glock 29:

180gr FMJ... 14.3gr AA9... 1250-1275fps? (This load is over Accurate's max of 13.5gr at around 1240fps, but I've seen no signs of over presssure)

165gr GoldDot... 14.8gr AA9... 1300-1325fps? (This load is slightly under Accurate's max of 15gr at around 1341fps. This is my current carry load.)

I used to load 155gr XTP's over 14.9gr's of #9 and CCI 300 primers. 1.26" COL. Ended up about 1320 fps.

Now I load 180gr XTP's over 13.8 gr's of #9 and CCI 300 primer. 1.26" COL. In my buddies chrony, that round was going 1200 fps. That is slower than everybody else's fps with that same load, which seems to be 1230 to 1250. But his chrony seems pretty slow. None of my rifle cartridges were within 200 fps of the box flap, and I have a longer barrel on my .223 than the test barrel from Hornady.

Who knows.

14.3 grains is technically over Accurate's current data. However they formerly listed XTP and FMJ data separately. The 13.5 grain max was for the XTP. It is a relatively long bullet. The max for an FMJ was 14.5. In later editions, Accurate has consolidated some of their load data and has left the more conservative figures. This is true for 200 grain loads as well. Velocities reported by Accurate have consistently been optimistic - at least in my G20. They seem to track closer to Hornady's velocities.

The 180 grain velocities might be optimistic for your 29 since that is about what I am seeing in my G20 for the charge you describe. So the usual velocity reductions are in order. I am not sure what they would be.

I carry a 165 gr Gold Dot over Accurate #9 and a CCI 350 (Mag) primer. 15.2 grains gets 1335 fps in my G20. The Speer max is 15.5 grains. They call for a mag primer, but I am sure that a WLP would work fine. To get the velocities that you are looking for in your G29, you might consider working closer to Speer's max data. They ran fine in my G20. No excessive pressure indications at all. However, the load you are currently carrying would no doubt be a good one.

I hope that helps.

With a mag primer, I am about 15 fps faster through my chrony, so your data sounds reasonable.

I would say that AA#9 is the safest powder that can
be used in 10mm pistol shooting because no matter
what weight bullet you want to shoot, I dont think
you can put enough powder in the case to ever cause
a problem. Once you get below 165 grains, you run
out of case space and you cannot even get to the
maximum SAAMI pressure spec. Even then it produces
the highest book max velocities compared to all other
powders on the market. ( 155gr JHP)

For those reasons,
it is my favorite and I cannot see any other powder
competing with it with the possible exception of LongShot.

AA# 9 may not produce the ultimate way over SAAMI
pressure velocities as have 800X, PowerPistol, BlueDot
and some others at hi powder quantities, but what it
does produce is known and predictable and most of
all respectable if not nuclear performance.

Can someone post the Speer data for AA9 in 165gr? I only have the Lyman manual.

Speer #14 list the 165 grain GD or TMJ FN COAL of 1.255" with AA#9 and the CCI350 as 14.5 @ 1277 fps and with 15.5 @ 1344Fps
