Copied from one of my previous posts. Just to lazy to rewrite it.
Its been two years since I figured out the PPM and it is still performing excellently.
COPY:
I am using my 2nd PPM now. I had sold my 1st one when I became frustrated with it while dropping flake powders. (Unique)
I found I really liked using the RCBS Uniflow. It drops Unique real well for me.
It works so well That I can use it on my progressive press to drop Unique.
I now have it all linked up with the case activated linkage. So unless I feel like dismantling it every time I want to drop a few loads.
So until I get a 2nd Uniflow or a Lyman 55. Its PPM time.
As soon as I got this 2nd one. All the reasons I got rid of the 1st one came back. Looking for a 6 grain drop get from 4.9 to 6.3. Usually it seems to error light as long as your set load was a full packed measure.
I also tried this with Herco and Blue dot. all flake powders. Basically same results.
Cant get pissed this time because I came into this one with eyes wide open.
Some people say they are a piece of crap, your a dummy for buying one esp 2 of them.
Then there are guys that are using them with no problems.
Since (My brother from another Mother) has never recommended any thing bad to me. I figure I better keep after this thing. ( history over)
I think I finally got this PPM figured out. After looking at it closely you notice its a small hole filling a bigger cavity.
Unlike the Uniflow where you have a big powder hopper filling the smaller drop.
With the PPM it IS all about the tap. Or in my case tap tap--- Tap tap.
I cant say that Just start tapping and it will work. What I found was after doing a few hundred Unique and Herco loads. I found I needed to use the trickler less and less. Then i noticed I made a whole run at 6 gr of Unique and did not trickle once.
" Lets test this"
I found that tapping on the screw twice on the up stroke and then twice on the down stroke was filling the drop as needed. Sorry for the dark image. my hand was covering the flash. Seems I am a right handed photo taker.
That tap spot for me seems to be the sweet spot. Tapping any where else did not seem to work so well. Tap right on the screw.
I set it up for 6 gr of Herco.
Then ran 10 drops making sure to follow the exact tap procedure.
So I can get Herco to with in 2 tenths of a grain in ten drops.
I can sure live with that.
I tried the same test with 6 gr of Unique.
I got 59.9 gr across ten drops.
Not sure I 100% trust this thing yet, but I am not afraid to use it for my flake powder.
