Powder measure for Accurate #9?

[WR Moore]

I've started experimenting with #9 for 44 Magnum and the fine flakes bind up my Lyman 55s and old Pacific bushing press. Given the amount of .44 I shoot weighing each charge isn't that much of a burden, but just out of curiosity, which measures work well with this powder?

This one.

I had a Lyman for a million years. The Redding is better in every way.

 

[WR Moore]

OK, which Redding?

I've only used a Dillon powder measure with AA#9. I've had zero issues.

 

[imakmst]

I've used AA#9 in my Hornady LNL measure with no issues

The RCBS uniflow owned has worked with all the fine grained powders used. AA9,7,5,2 H110, lil gun etc. It works well with unique, although hitches a little on occasion as it cuts through.

Lee scoops can be easily reduced by stuffing aluminum foil in with a dowel. Put a ball of foil in the scoop, then alternate weighing and compressing the foil till you get the charge you want. Then mark it for that loading.
I've never had one change volume and if it did it would be lighter, not heavier.

On another note, a local shop was selling out their stock of AA#9 for $20/pound. I grabbed a couple. Wish I got more, but I'd never used it before. It works good in 168g SWC 357 loads for my rifle.

Redding 25 works well for me with AA9, but I've not encountered any problems with my Lyman 55, either. With the Lyman, I keep the large drum closed and use the two smaller slides.

AA#9 is a fine grain spherical powder, it should meter well in just about any rotary powder measure.

#9 is not flakes...........Its granular........Ran through my Lyman 55 with no problems.......Mebbe ya need to take yours down and clean it good then lube with graphite powder.

Try setting the slides to form one narrow deep cavity with as little powder showing at the top of the cavity as possible ... lots of folks don't know about this trick and it helps .
I have been using mine , orange Lyman 55 , with AA #2 and AA #5 and the narrow deep setting with no problems .

Another option ... Scoop .
I make little powder scoops to dip the weight I want ... and scooped charges can be extremely fast and accurate ...
I hate resetting my 55 once I have it set to a powder and weight I like . Scoops are cheap to make .

The 55 I tried the #9 in was set for 6.4 gr Power Pistol/6.2 gr BE86 and I know about the deep thing. The issue seemed to be fit between drum and measure body.

My experience with the RCBS was enough that I've never bought another after I had to rework the thing to throw stick powder (4198) reliably. Excessive clearance between chamber and the adjustment stem end piece. OK, everyone has a few examples that aren't the epitome of precision, but DAMN!

I find that fine powders like that measure well with any good measure (that doesn't have a lot of slop). When in doubt I resort to an old Belding & Mull Visible Loader, slow but accurate. If you get a Harrell, your measuring difficulties will disappear… along with a lot of your dollars. Very pricey, but super accurate.

I've used AA#9 in my Hornady LNL measure with no issues

So have I.

 

[LAH]

That powder is very fine and if there's any slop at all it's going in and caused binding. My Dillon measures do real good and so does my RCBS Uniflo. To be honest I've never tried it in my Lyman 55.

 

[danlbobb]

I use a Lyman 55 with AA9 and AA5 with no binding.
I use the top two slides.

When noting else works ... drop back to basic's and make a powder scoop and get to dipping them charges .
If you have some old Lee dies ... a scoop used to come with each set and of course a scoop came with every Lee Whack-A-Mole Classic Loader ... break one out and see what it'ii do .

Whatever measure you use always use a powder baffle:

Guys, I appreciate the advice, however: I've had a set of Lee dippers since the late '60s*. While I can use them and a scale, that's rather time consuming, but doable if necessary. I might well end up weighing each charge. I haven't had baffles in my measures that long, but they didn't make any difference. Teeny, tiny granules will manage to work their way into spaces where they don't belong and bind the measures. That 55 works great with 748-and a few others.

One thing I did discover over decades is that a measure set for one particular powder charge might also drop a usable amount of another powder without adjustment. Worst case, you have to trickle a wee bit more to get it exact.

*That's 1960's.

WRM, AA-9 has been my favorite "slow" powder for years. I can't recall if I used it with other powder measures, but have used it in a Dillon powder measure for years without issue. Yes, "teeny, tiny granules", and flows like water through the Dillon, equaling very consistent velocities. I have an old set of Lee dippers around here too. Yep, doable, but tedious..
