How important is one kernel of powder?

A fellow shooter once quotedd someone...or perhaps made it up himself; I don'trecall. But what he said was: "Half the stuff we do (with regard to handloading competition ammo) probably doesn't make any difference...we just don't know which half."
1/2 kernel accuracy already exists. It just currently isn’t possible with an auto trickler system. U can individually weigh powder to that 1/2 kernel target but u will take some time doing it.Nooooo!...…........... you can't just leave it be.

With the Sartorius 503, u can weight to .01-.02 gr. One kernel of Varget is heavier than that. Each powder throw n trickle up will end up at a different end weight that is out of that range. It may take two or three times to hit that small target weight but it can be done. Just takes time. Auto tricklers don’t have that fidelity and doubt they will. They are limited by the per kernel wt. variation of the powder.
Yeah my post was in jest, just to illustrate the never ending obsessiveness we can have with this. The only way an Autotricker could meter to the 1/2 kernel is if it had a kernel cutter built in.
My Sartorius Entris weighs to .001 grains, so if I wanted to I could cut kernels. One kernel of Varget typically weighs .018 to .022 grains. That is useless info, and is now why I use the A&D FX-120i and am happy to be within one kernel, and I do have a method that keeps me to a 1 kernel variance. Not plus or minus one kernel, but one kernel. That is obsessive enough.........
Imagine how many variables we, as handloaders, have control over. All depends how far your dedication will take you. Handloaders agonize over the slightest variable and will spend countless dollars to make the "perfect" cartridge. They have total control over said cartridge.
And then they shoot at a target WiThOUT using wind flags. Once that "perfect" round is fired the shooter has no control of it if there is the slightest breeze. Was the breeze the factor that caused the bullet to impact differently or the changes made during handloading?
Wind flags will open your eyes as to the bullet path. They can be as cheap or as expensive as you want.
They were the best investment I made for shooting accurately.

I don't mean that literally (but I bet it's not far off!). I mean in an idealized theoretical energy balance sort of way. The "all else equal" is VERY important in that statement. I was just illustrating that you can mathematically and explicity show that smaller cartridges are more sensitive using fundamental physics. Intuitively, this is obvious, of course. But you can also prove it (as I did).
The assumptions I made are that the same powder is used in each case and that all of the energy in that powder is turned into the bullet's kinetic energy. In real life that is not the case, but that doesn't matter for the purposes of my earlier post.
Well Stan, You “Do” have a wall of “WOOD” !
Since You are a nice guy, I may show You how to accurately weigh to .02 grains with a $25 investment.
But You will have to put down the cigarette

When I consider my strategy for handloading, it often incorporates many variables. Chief among them is accuracy and precision. However, there are other variables to consider, such as time, effort, and cost.
I usually ignore cost, because across a long enough timeline, I can always find a way to produce the money required. There's also the experience factor to consider. I really enjoy my time spent at the reloading bench, specifically because of the quality of tools I choose to employ there. The high end machines make it as stress free as possible.
Time and effort can sometimes be mutually exclusive. So I run the strategy through the logic in my brain to determine what level of expected accuracy, precision, or uniformity I am trying to achieve... and weigh that against the time and effort required to get there.
In the case of weighing powder to a single kernel, the Prometheus powder measure allows me to do that faster than any other device, with less effort, and achieves charge uniformity which is unrivaled by any other device. So, there's no reason for me not to throw charges to the exact kernel of powder each time. I know it has produced better results on target than anything else I was using prior. So the justification for me to continue doing it and recommending others do it, is self evident to me.

Also, not sure if this was said above, some barrels are at a length where they would shoot a given load faster, if they were actually cut a bit shorter. That could be thought of as a fairly dead zone where friction and decreasing pressure are close to parity in negating V gain. For those barrel/load combinations, a small increase in powder may actually net zero or a less than expected additional velocity gain, like the extra length is doing.

As a Short Range Benchrest Shooter, both group and score, I never load at home. Period, Heck, most of the time my loading equipment, minus the powder, just stays in my truck.
I have shot 10-shot “ones” with my Rail Gun where there was 30 FPS difference in the ve,ocities. It just does not matter at 100/200/300 yards.
for years I just threw charges out of a Hensley powder measure. I now use a ChargeMaster Lite. I honestly can’t say that anything has changed.
As 600 to 1000 yards, I think minor differences in the powder charge can make a measurable difference. How much depends on the particulars at the moment.
I will say this. Many guys that are worried about on kernel of powder are shooting bullets that simply don’t know the difference. You can’t shoot 1/4 minutes MOA with 1/2 MOA bullets.
PM commin at You Stanley. I can’t give away all My secrets on the i net.He He
buckwheat huh…just glad it’s not huckleberry, or range b#@ch
okay. I’ll be waiting for your message!
