Lee Perfect Powder Measure

I know its an old thread but just to say that I got a positive improvement on consistency just by making a baffle to fit on the bottom of the bottle. Same design of the other brands but made out of neoprene.
Coming from a different brand of powder measure, I must say that I am very impressed with the utility of another Lee product.
 
I have the Lee Powder measure and it always seemed to work well. I did spray down through it with anti static spray when it was new and let it dry. Most of the time it will hold to about half a tenth. One important thing is after you throw the lever, firmly tap the side a couple times to dislodge any powder still inside. I've used it with CFE223, Bullseye, and Longshot powders with no leakage problems.
 
I had a Lee PPM and wore it out in short order. Ball powders, like glass...go to a flake and it got a little iffy. Stick powders, forget it. That plastic drum got gouges in it from cutting logs. Too slow and inconsistent for me. For the new shooter, or someone loading 20/40/60 rounds, it may work fine.

Don't know why the posters on the earlier page had problems with the Lyman #55 powder measure. I have used mine a lot and when you set it on ball or flake, it is within a .1 every time. Have to do the sequence of taps tho....Up - Tap, pause, Down - tap tap, pause. Doing a tray of pistol cases like 357s took a minute or two (50) tap, taptap,move, tap, taptap, move, tap, taptap, move, etc. When I got used to it, 200 pistol rounds on the single stage press in an hour was not abnormal sitting.....with stick powders, I dropped within -.5 and trickled the balance. When loading H4831 and similar, it would go +-.2, but that is a .4 grain spread...to much variation for what I wanted. Short load and trickle the balance is the way to go on the stick powders.

I have the Lyman # 55, a Lyman pistol powder measure with the brass inserts, an RCBS, and several Dillons. The Lyman # 55 is mounted on my bench, the RCBS is mounted on my portable stand with the Rock Chucker (it cuts logs easy with that long handle and is better than running the electric scale when dumping 70+ grains in a load.) When loading volume (ball powders), I use the Dillon on the progressive presses. I bring out the scale and start setting the charge bar. I will not stop adjusting until I have thrown at least three charges in a row that are exactly the same. The other day I was loading up some 22 Hornet using Lil Gun. Charge was 12.5gr. That was my first try with that powder so I was being really picky. Did 4 in a row....50.0 on the scale...went two more....75.0...and two more...100.0. Figured if I could throw 8 and hit the number right on, I wasn't going to get anything better.

Consistency in rhythm and motion is important when trying to throw consistent powder charges. This becomes doubly important the smaller the diameter of the case neck.
