The book is at 13.5 max so I loaded at 13 as I had to switch from large pistol primers to large pistol max primers but like a safety margin anyway. What does anyone think of this load?? I will shoot tomorrow. I have used AA9 in 357 for Desert Eagle in the past with no problems. Craig
Craig, Accurate #9 has undergone several changes over the years. My first experience with AA#9 was back when it was 100% microbead which was all Winchester 820.
Later they blended Winchester 350 with the 820 (the % of the blend also changed) No 9 Blend (WC 820 90%, WC 350 10% - 106/94)
Then they blended IMI#7 with the 820 No 9 Blend (IMI No7 20%, WC 820 80% - 118/92)
Now the newest is all flattened ball powder and is much better in my opinion that some of the older blends...
However the loading data never changed as the formulas were to make the same pressure values.
Hey Wade thanks for the input. I have had this powder for 10 years or so so that is one reason I load light with it. It was a very powerful round in 357 and I think I may have loaded it in 10MM but don't remember. Anyway it ought to be fun. Craig
I like #9 for the velocity and accuracy I get in 10mm. It also has a reasonable safety margin built into the process, which is you usually can't seat a bullet over a dangerous charge weight in 10mm. Max loads are usually very compressed.
The downside of #9 is you are using 60-70% or so more powder than a comparable load with Longshot or BE-86. And #9 usually costs more than other powders per pound. Last time I did the math, it was easily the most expensive powder per shot to use in 10mm, by almost double in some cases.
I keep a pound on hand, but I don't reach for it often.
Well I shot the 10MM AA9 loads today and all I can say is WOW, WOW, WOW. Much stronger than my Power Pistol load but they were loaded very light max being 9.3 and I think I loaded like 6 or 7 but not sure as it was awhile ago. The AA9 loads at 13.0 I could have shot all day but was loosing brass so I stopped!!! I guess I shot like 20 rounds or less but only found 13 empties. Real fun though. Craig
13g of AA9? Do ypu know where you are at velocity wise and are you using 180g bullets????
No idea on speed and 180g bullet. Craig
AA9 @ 14.0 with 200 XTP for 1250 fps in G20 with 4.6" KKM barrel using CCI 350 Mag Primers clean burn and excellent accuracy 1250 fps trail load.
I use No. 9 for 2 of my main loads.
My pet load is 14.5gr #9
180 gr armscor bullet
1.260" COL.
I shoot them out of an AR carbine. She's spicy. Around 1550 fps'ish
This powder is several years old and I've shot a lot of it. Probably near a decade if I were guessing.
Have also used in with 155 gr hornady xtp bullets. 14.3-15.9 gr no. 9 powder. fps averages with them is around 1770 fps (again out of a carbine length barrel).
I have heard that they've changed the recipe. And I do know that hornady later changed the load data after their 9th edition book came out.
So far though, I've had no issues shooting that load in my gun. I know that's a sample of 1, but that has been my experience and the load data that I go to.
Lately, I've been shooting a lot of the 175 gr Lee cast/powder coated bullets. And hard cast 180's for hunting using the spicy stuff and so far, no issues.
In knowing that they have changed the powder recipe, if I ever run out of the no.9, I'll drop it down to whatever the current data shows.
