For my large rifles, I always load single stage. I also always use a trickler along with a Gempro 250 or a Frankford Arsenal Platinum digital scale. The Gempro is by far the best and has been extremely accurate over the years. I also have a couple Frankfort Arsenal DS-750 digital scales for reloading on the move. They are cheap and accurate if you take your time with them.

Not sure if you have re-programmed your CM yet. Changing the perimeters will stop most of your overthrow. I just got started with one last week and have enjoyed optimizing it. Youtube is your friend. I don't use it for ball powders. Just stick. Plain ole powder measure will always be the bomb for ball powders.

IMR-4064 does not throw well from any measure that I am aware of. I have never tried Lee "Perfect" powder measure, but people have reported it works well with extruded powders. It's made of plastic and is very cheap. It might be worth trying simply because it's so inexpensive.
I never tried one because I have a mental block against buying plastic tools of any kind. Old prejudices die hard. |

I saw all the posts about it throwing extruded well and bought one to try for myself. I've played with mine and it does throw extruded + or - .1 gr. I will try IMR-4064 next time I have it out. I bought it to throw 800X, which it does fine. + or - .1 gr. My Redding throws flake powder fine until I tried 800X. + or - .4 gr not acceptable for me. Like any PM you must use good technique to get good results. |

I have not tried 4064 but I have been loading IMR 4895 and the charges are +/- 0.1 grains. |

Given the good reviews (and the low price) I have ordered a Lee Perfect Powder Measure. Thanks for the help!

I've got the measure mounted to my table and I ran a pound of powder through it to damp out the static.
What kind of accuracy should I expect? I'm getting variations of about +-0.3 gr on a load of 47 gr of IMR 4046. 1% should be accurate enough. There's no safety issue as the max load is 52 gr, I would like to be closer if I can be. Also, will I see the same variance when I load 300 blackout (IMR 4227) or .223 (Varget or TAC)? +-0.3 is a bigger deal with the load is only 10 gr. |

Powdered graphite applied with an acid brush works much faster than the coating on the powder. Also powdered graphite is the best static killer available. Dryer sheets work ok, just not as good. 2. PM tuned? It's easy see thread below. 3. Terrible, should measure exact. With tuned PM and good technique. See thread below. 4. Learn how to throw accurate changes, then no worries. https://www.ar15.com/forums/armory/Tuning-a-Uniflow-powder-measure/42-380281/ Works for all PM's. https://www.ar15.com/forums/armory/How-to-get-accurate-charges-with-powder-measures/42-520135/ I have used my Lee PPM since writing this thread, and this thread can be applied to the Lee PPM. |

As others have stated and I will echo, for my large rifles that consume the larger stick powders, I always use my Gempro, trickler and load them all on a single stage press. I for one will not bother with the automatic charge throwers, I find they all tend to have their issues and become somewhat erratic over time. If you want to speed it up a bit and do not require better than +/- .2 grain accuracy you can use the standard Lee Perfect Powder Measures, they are worth the money if you are wanting to load large rifle rounds in a timely manner and do not need ultra precision.
And just an after though. The Lee Perfects are awesome for stick powders, but ball powders forget it, they tend to leak enough to be annoying and make a mess. |

Yep, the one I received(and returned) was all plastic and sifted powder out the sides of the drum during use. That was with flake powder. Complete crap IMHO |

@dryflash3
Thanks for the links. I did the tap to settle trick and installed a baffle (drilled prescription bottle lid) and was able to throw five 47.0 gr charges in a row. (Still need to work on my technique though.) |
