weight of one kernal of powder

Butch, ya I realize that about everytime I shoot in a breeze. heh heh. Just looking to speed up the reload time. Thanks
My dropped loads seem to be more accurate than my weighed loads . I use a Harrels measure to drop loads for my 6ppc and my 6BR score gun , and they shoot better than weighed loads . I know why that is . It's because powder gains weight with moisture with exposure to air . So your kernals that weigh whatever today are going to weigh more depending on how much moisture they absorb , and this goes on depending on how long that powder container is open . A dropped load is measured by volume and a weighed load is measured by weight of course . There is also a tremendous difference in the moisture content lot to lot , depending where and how it was stored after manufacturing . So don't leave that powder in the Chargemaster and don't leave the container open , screw that lid on . Use the cheapest scale you can buy , 1/10 of a grain is close enough ;D!

I get a heck of lot more "picky" on the charge weights then I do case + bullet weights, and can see the vertical advantage on the targets, and agree is more important at LR.

Donavan,

I am only talking about 2 kernels of Varget. Will this amount make a difference in my accuracy @ 600yds?

Thanks, Dennis

Dennis,

I feel it makes a difference only to the difference of what case your referring to. In a large case, say a 300WM down to say a .308 case, no I don't feel that two kernals really makes a difference.
But say in a smaller case like the 223Rem, yes, I feel that there could indeed be a difference.
 
This is an interesting topic. Personally I have found the more attention to detail I pay to the reloading process the better results I receive in my scores. I have to believe all this increases my confidence in the equipment and translates into better scores.
I do agree that being able to read the wind/mirage is a key component that trumps a lot of this but it does not hurt to have accurate equipment to start with when your skill (read mine) is not necessarily that of a John Whidden or Sheri Gallagher.
 
A charge differential of .02gr on a 33gr charge hardly registers on a chrono or the target but I still weigh charges to the .02gr resolution of my scales.

However, a 1mph wind velocity change WILL move a bullet two inches at 600yds....much more than that .02/one kernel charge differential.
 
Understand that.. if you have a variation of +- .02 grains, which could be a inside the bell of .04 spread, which is almost half of a tenth of a grain. And .1 grain can make a difference in a 223 case. So in some cases your not going to see any differences.. in others you might. I know that I have seen some bad verticale due to spreads in the load. And they were not big spreads either. One tenth in a 223 can change the whole aspect of shooting 2 inches to 10 inch verticle at 600 yards..
 
Granted a granule or two can't make much difference. The question that haunts me is can it be enough to make the difference between touching and not touching the next scoring ring? Think about that next time you need to plug a shot! ;D
 
I think H1000 should weight between .025 - .035 gr.

What you guys are missing is that a scale like the GD-503 not only weighs powder down to .005 gr. One kernel accuracy might not make a difference, but the fact that these scales don't drift might be what makes the difference.

I know for a fact that a Chargemaster will vary as much as .2 gr while still reading the same on the display. Take that level of inacuracy and add drift and now you are way off your intended charge.

Some people refuse to do things that will make their loads more accurate (weigh to single kernel accuracy), and instead spend hours doing things that do nothing for accuracy (like sorting bullets from base to ogive).
 
My testing at 1k, with a dasher shooting the hybrid around 3030fps shows .1gr.= 1.5'' vertical. If you use a chargemaster and do not weight out your charge again on a better scale you will have 3'' vertical from charge weight alone. I don't understand why someone would over look a way to shrink their groups. Yes, wind will effect the bullet more, so what? It doesn't take any more time to do. By the time the chargemaster has finished the next charge, I am done trickling the last one.
 
I think the question was 1 kernel, not .2 grain. Nobody is saying disregard a good reloading method, just 1 kernel is not as important as watching conditions.

If consistency of many small things equates to accuracy, I fail to see how controlling a major variable like powder charge to a very fine degree can do anything but increase my success. If that level of consistency is beyond necessary, then great, it is one less variable to worry about.

Wow I see the same arguments/statements/jealously on Snipershide when the subject of highly accurate scales comes up, fact is the winners of long range matches don't throw n load there charges, do I have a super accurate scale, why yes I do, a Gen 2 Prometheus, can I tell you what a single kernel of any powder weighs, nope, but I see a single kernel move the balance beam. Shooting is a triangle, shooter, ammo, and equipment, all 3 are equal.
 
Brian, You are right about the triangle. The shooter has to believe they have loaded perfect ammo, they have very good bench technique, and have very good equipment. From there on Mother Nature takes over and they have to decide whether they are a runner or a picker. All you can do is try to eliminate what variables that you can in Long Range BR. Ron
 
I have a tuned beam scale and can see the beam deflect from one kernel. It didn't cost thousands of dollars and I didn't have to wait for a year or more.

I agree with Erik's statement above. I always check my empty pan weight, this tells when you are off on your charge, and it's common for it to vary.

For the last few months I have checked my weight with two backup scales just to be sure.

The chargemaster will be dead on for maybe 15 loads, then all of a sudden, the 16th will be off! With all of the extra brass prep processes we do, it's well worth double checking my match loads.

I found the below statement "very" interesting. I am going to dig into this as soon as I can. I have never given this a thought. But it makes since.

I have recommended your tuning abilities many times and will continue to do so, but my scale is not only super accurate, it's also automatic, every 8-10 seconds its ready to charge a case, I charged and seated 200 rounds in 50 minutes the other day.
 
I mentioned this some time ago and thought I'd mentioned it again in this thread:

After I calibrate my GD503, I place the pan on the scale and rezero. I fill the pan with a scoop and trickle up to my charge weight. Each load goes into the pan in a zero state. I know some folks load their pan and then place it on the scale, but I prefer to start in a zero state. Maybe this doesn't make nary a difference with this scale, but it makes me feel better.
