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?

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.
 
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.

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.
