aa9

[Lloyd Smale]

have to chuckle at brain pearces recent article in handloader. I should have know better as this has happened before but i just had to try it again. Ive been working up loads for two 45 colts. A stock ruger 4 5/8s blackhawk and a custom clements 4 inch vaquero. Ive been loading 6 differnt 45 bullets around 255-260 grain. So far i tried unique herco 2400 hs6 4227. I didnt use 110 because this is a slightly reduced loading im shooting for. Somewhere around 1000-1100 fps. Nothing earth shattering but some decent groups up to this point. then i figured id give aa9 a shot. I usually dont use it for reduced loads as ive found it hard to ignite like 110/296. Well i loaded up all the bullets with 19 grains of aa9 using both cci 300s and 350s. I started shooting the ones with 300s and had squibs in every cylinder full and a couple that barely made it out of the barrel. It had my wondering if my powder measures was hanging up. I then shot the ones with 350s and low and behold not a single squib or light recoiling round. Another good thing was that hands down both of these guns liked this load better then any other powder primer combo. It shot the old lee group buy 255swc and babores 260lfn into one ragged hole at 25 yards in both guns. Sorry brain but your never going to convince me you actually shot those test rounds using standard primers. More then likely you were looking to make a dedline and wrote a tale. By the way it was 40 degrees when i shot and im sure if it were colder the results would have been even more of a joke.

Very similar results for me :

AA9 is one of the best"reduced" loads in my 480's. 18 gr under a 420 gives me 1100 fps with 100 yd groups of 3'' or so. A plus is that it hits the same spot as the same weight bullet at 1275 at 100 yds. Shoots great in the Alaskan too.

Pearce has written a couple of things lately where I think he's gone off the rails.

That said, in my .45 Colt and .41 Magnum loads, AA #9 has done well for me atop WLP primers.

Lloyd;
I must confess that your comments trouble me. I have never met Brian Pearce but I have read his articles, critically, for the past three years or so, and find that we have MANY common experiences. You are, in effect, merely because of differing experiences calling him a liar. THAT troubles me.

Let me give you an example. Many years ago (probably 40 years or so), before I even stocked magnum primers, I wanted to change powders for "high end" loads in my Model 24 S&W. This was and is a 6½" barreled revolver chambered, as you know, in .44 Special. I didn't like 2400 due to the unburned powder left in the barrel. I wanted something a bit cleaner.

H110 was just becoming popular so I thought I would try some. I checked the manuals and loaded a safe starting load (as outlined in one or two manuals). The second shot I stuck a bullet in the barrel. I carefully removed the bullet (a 250 gr Keith) and a shot or two later, stuck another bullet. Obviously, something had to change.

I went home, chastened, but not out, and did a bit of research. I did some measuring and discovered that the old set of .44 Special dies gave a minimum of neck tension (that had worked perfectly with loads of Bullseye powder and Unique powder. I had been teetering back and forth about ordering a set of RCBS carbide dies for the .44 Special/Magnum and decided my full length steel die just did not size my cases down far enough to give proper neck tension. I hoped that the new sizing die would solve this. Money was really tight for a man with a growing family and the delay was occasioned by the cost.

At any rate, I got the new dies, and along with the blessing of sizing cases easier and without lube, I NOW had considerably more neck tension for my home cast Keith 250 gr bullets (Lyman 429421). I have since fired thousands upon thousands of H110 loads in the .44 Special and .44 Magnum and have never had any "bloopers" since. In the past I had several bad experiences with CCI primers so had settled on Federal 150's or Winchester LP primers and have seldom used magnum primers.

So, my comment to you is I believe your account of your experiences but I also believe Brian Pearce's account of his experiences. There has obviously been something different that caused those differences but I do not, for one minute, believe that Brian is lying. To assume he is lying tends to belittle you and the rest of us on this Forum.

This is NOT a personal attack on you, Lloyd as I respect you and your experiences - I just believe it has become popular to pan writers whether there is any reason or not and this appears to be one of those times.

Let's play nice, shall we??

Dale i wrote a long reply to your post and then deleted it. Sufice to say that i stand by my results and if Brain cares to argue them id gladly meet him half way with components and my chorograph.

I would bet there are as many versions of AA9 out there as there are WC820s. Keep in mind the variance in storage conditions of the various lots as well, including the actual formulation differences however slight. Ignition results can be significantly different, especially in different applications than intended (case full, case half-full, bore size, boolit weight, etc.). ... felix

[Lloyd Smale]

Felix my complaint with the article is he claimed it was a good powder for reduced loads and claimed it worked best at those levels with standard primers. Just aint happening with aa9 or 820 at least with any batch ive had and ive been using them both since they were available and probably shoot 2 times as much of it as all the other powders i use combined. By the way your absoultely right about the burning rate of aa9 varying as much as 820.

[btroj]

I once had squid problems with WC820 in my 44mag super redhawk. Got tired of pounding bullets out of the barrel with a wad of powder stuck behind them.
I crimped them to holy h*** and got them to all go off. Talk about velocity variation!

These were with standard primers. Don't know what mag primers would have done. I do know that in that gun WC820 is reserved to magnum type loads only and the bullets are crimped heavily. I also have tried to keep bullet pull without crimp to its max.

I feel your pain in squibs. Once was enough to teach me.

I’m not sure I completely understand this topic. But here goes my thoughts…

I am shooting the Lyman 429650 (320 grains) from a SRH…

I had been using CCI-350’s all of the time with AA#9 and WC-820…
(My lots of AA#9 and WC-820 are the “same”)

The charge for each of those powders is 15.0 grains…

I shoot this load as a long distance “fun” load. By that I mean I have a life-size silhouette of a groundhog that I place at 150 yards. The SRH is ‘scoped and I can rattle it close to 80% of the time…

Well, checking my supply of 350’s I discovered that I was getting rather low, but I have several thousand CCI-300’s. So I wondered about just switching to the 300’s and giving it a try…

I did not chronograph the 300’s versus the 350’s, but I was amazed that the P.O.I. stayed the same at the 150 yard target. So apparently there isn’t any, or much, difference in velocity generated by the 350’s or the 300’s…

Accurate Arms reloading manual recommends a starting load of 15.7 grains, so I a 0.7 grain under the starting load…

Accurate Arms also recommends the CCI-300 and not magnum primers…

So I guess I am saying that I never had any problem using AA#9 or WC-820 with regular primers…

(I am also using 300’s with the AA#9 and WC-820 in the 45LC with the 45-270-SAA and no problems either)…

Bear in mind that the Winchester large pistol primers are listed right on the box as being for Magnum AND Nonmagnum applications. Win doesn't make a spcifically-Magnum LP primer.

That said, I have great success with a 240gr WQ-WW semiwadcutter with #9 and a Win LP primer in my 7.5" Super Redhawk. Or a Nosler 240-JSP, more #9, and a CCI Mag primer.

[Shuz]

FWIW: I've never used AA9 in the .44 mag, but I have burned thru several jugs of WC820 down thru the years and I have never experienced a squib load. I have used CCI 350 mag primers exclusively. I will mention that I load on a Dillon Square Deal B that has a minimum size expander button/ball. IIRC it is .424 in diam. My favorite WC 820 load with lot number 47320, is "only" 17g, CCI 350, 429421, at Saeco 7 and weighing 252g and sized .431. OAL is 1.710. This load is very comfortable to shoot in a 5 inch bbl'd Smith 629, and gives 5 hole groups of less than 1 inch at 25 yds from a rest. Now the interesting info: The velocity is 1144fps, es 66 and sd of 28. Not stellar stats, except for the velocity. I attribute the accuracy and velocity to the very stiff case tension caused by the smallish expander.

[Dale53]

Lloyd;
I am with you on this. I would NEVER try using WC 820 or AA#9 for reduced loads of ANYTHING. I have used a bushel of WC 820 over the years but NEVER in reduced loads. I have the original lot # (a slow lot of WC 820) and it is within .5 gr (half grain) of H110 and I treat it just like I would H110 and Win 296 (nearly full loads or full loads only).

Years ago I chronographed my loads in both my S&W Model 29 (8 3/8" barrel) and my Ruger Red Hawk (7½" barrel) and 23.0 grs gave me 1200 fps with a 250 gr Keith and 24.0 grs gave me 1300 fps. I practiced with the 23.0 gr load and hunted with the 24.0 gr load.

I also am a BELIEVER in case neck tension. My problems with H110 in my .44 Special were totally relieved by increasing case neck tension. That was proof enough for me.

FWIW

I wanted to chime in here because I am so new to reloading compared to the rest of you. I recently purchased a .41 magnum and loaded up twelve rounds to test Brian Pierce's load the other day, 210 grain semi-wadcutter over 18 grains of AA # 9 using the CCI 300 large pistol primer. The loads shot fine, so I loaded up another 100 the other morning. Like I said, the loads seemed fine, but are you guys saying you would recommend the CCI 350 primer instead?

Also, from what I am hearing, one should never try to use reduced loads with AA # 9, is that correct? I also loaded 15 rounds of .32 H & R magnum with 7.5 grains of AA # 9 and a CCI 500 primer using the Lee 90 grain tumble lube boolit. They shot fine through the Ruger SP-101 in .327 Federal.

Again, not trying to start an argument, because I don't know what you guys know, but just wanting clarification, would hate to have problems.

Are you guys saying you would recommend the CCI 350 primer instead?

Some people have had problems with standard primers and slow ball powders (myself included) and would advise that you use hotter primers with such powders. Others have not had the same experience (whether by luck or a difference in technique or possibly climate) and do not share that opinion. What I can say without doubt is that I've never heard of anyone having squib problems with H110, W296, Wcc820, or AA9 when using magnum primers. The same cannot be said for standard primers. If you are going to use standard primers, be aware that squibs may occur and be very attentive to changes in sound, feel, velocity (or lack there of) etc. The worst thing in the world isn't a squib load, its the full power load you fire after the squib.

Also, from what I am hearing, one should never try to use reduced loads with AA # 9, is that correct?

Some powders just are not good in reduced application as they need pressure to burn cleanly. The real slow burning ball pistol powders fall into this class.

In rifles, IMR 4350 is notoriously bad in reduced loads.

[BCB]

Is it possible there is a terminology misinterpretation here?...

By reduced load, are we talking about, say a charge of AA#9 in a 270 or 30-30 or some other rifle case with a cast boolit?...

If that's the case, then I agree it shouldn't be done...

But in applications it was designed to be used, I have never had a problem with CCI-300's...

The same is true with WC-820...

[turnercl]

My experience with AA#9 is loading 357 Maximum. I made some trial loads of 2400, Lil'Gun and #9 all over Winchester Small Magnum Pistol Primers. These loads were each about 10% under their respective published maximums. No problems with the 2400 or the Lil'Gun.

However the #9 load was over pressure (flattened primers, difficult cartridge extraction). Subsequently I read comments that Win small mag pistol primers were way hot and probably should not be used unless a load recipe specifically called for them.

Reloading with small rifle primers (not mag) solved my #9 pressure problem.

So my theory is that #9 (more so than 2400 or Lil'Gun anyway) can be pushed over the edge by a too hot primer.

By reduced load, I meant anything under published minimums or anything with lots of air space left in the case.

The .32 H&R load in question only fills about 67% of the powder space with the bullet seated to .250 depth (which is about as deep as one can seat it). I would suspect other powders would be better in that application as I've never known AA#9 to be very consistent when given 30% air space to work with.

[MT Gianni]

John Taffin recommended a charge of 15gr-16 gr of AA9 in 30-30 and a 180gr RCBS. I have had good luck with 15.7 gr charge of WC820. I would not shoot AA9 in a low pressure load and don't consider this to be one. AIRC velocity is around 1700 fps.

[exile]

Thanks for the information.

I seated my 90 grain tumble lube boolits out a little farther since I am putting them in a .327 Federal revolver, thinking that would decrease pressure a little bit. Maybe that's not a good idea.

Also someone gave me 100 Winchester large pistol primers which I was thinking of trying in the .41 magnum with AA # 9. Maybe that's not a good idea either.

So much to learn, hopefully without blowing up any guns.
