Powder charges..

[Julios]

Got a question guys, how accurate the powder drop is, on every charge I get a bit different reading and I checked it on 2 different scales..
I have the lnl ap..

Accuracy differs with each powder system and the type of powder that you are using? The finer ball powders drop with more consistency and stick powders can be all over the pace. What powder are you using and what is your weight deviation?

Pistol or rifle charge....what powder(s). Also, are you using a digital scale, mine fluctuates a bit that 's why I rely on a balance beam for consistency.

To get consistent drops I have to "knock or tap" the handle of the powder measure a few times (3), each time to get the powder to settle. I too use a beam style scale and generally get .1gr or less variance. I use a Redding 3BR measure.

HS6, I'm doing few 115gr 9mm , I started with the lowest gr. 5.7,I do get around 6 out of 10 shots but then it goes to 5.8 sometimes 5.9 then down to 5.8,5.7..

Pistol,HS6 powder with rem primers,and I used 2 digital scales..

While some powders meter more consistently than others, there is at least a tenth of a grain variation in the scale and another tenth of a grain variation in the powder measure. So there will likely be at least two tenths of a grain variation from charge to charge - not enough to have an effect on accuracy, really. There are other factors like static, temperature in the room, etc. Operating the handle at the same speed & hitting the stops up & down with the same impact each time will help.

I clean a new powder measure's drum with alcohol & run about 50 powder drops before weighing to coat the inside of the drum with powder residue. And before charging cases, I'll drop at least 10 charges to settle the powder in the hopper.

Ok,good to know,thanks..

I been also weighing a complete round on one I have around 182.4,other 185.6.. and it should be around 5.7 5.8gr on those two rounds..

Win231 had it all right.

Don't bother weighing finished rounds, the variance in brass, bullet weight makes it impossible to tell anything about the powder charge.

Ok good, measuring everything it's making crazy lol

Like others have stated, clean the powder drop thoroughly. I myself use HS6 in the LNL and have had consistent measurements, in regards to charge weight.

[Julios]

Ok,I'll try that..

YES it will. Try weighing a hand full of projectiles and a hand full of empty brass and see how much variance you get between them.

As for powder drop when you actuate your powder drop you should be consistent with how you throw the lever. I am rather aggressive so that it will settle the powder with each throw, but it also makes things more consistent. If you are soft once and violent the next time you will get a lot of variance.
