Is your aiming accuracy @1000 comparable to one kernel?

[Alex Wheeler]

Of course if we load the wrong recipe, they won't shoot if we hold one millionth of a kernel!

Tom

Truth!

 

[Stan Taylor]

.115 grains

I don't have the sophisticated scale you have mine said .12

 

[Stan Taylor]

Mine's probably a bit dry, ain't had a lid on it in 10 1/2 years!

Tom

Okay mine was probably in the fire that burnt my shop down lol.

A little OT but what have you guys discovered with runout, as measured on the bullet when it is seated in the case, do you serious winners measure your runout?

 

[ClassCat]

That is what we try to do in Short range Benchrest. Those are 5 shot groups

 

[ClassCat]

They are in the Bull, Does that count ? NOPE

 

[steve123]

I make sure the dummy round I use to find my touch point is perfect. I check a few if I change a die, or had a die removed to make sure everything is still decent. Besides that, the tool collects dust.

It's kind of like the seat pressure gauge, it depends what the cause is whether or not the target is effected. If your bullets are pressure ring dominant, picture a ball and socket, a little TIR doesn't show on paper. Provided it is measuring the bullet "leaning" in the neck, but if it's measuring a banana shaped case you need to fix the problem. Good cases, non pressure ring dominant bullets, good fl die to chamber match, and a decent process, I can't see it as possible to put one together with more than .0015" TIR.

Tom

Okay, got that, thanks Tom.

So once you've fired the cases are you checking the runout on all the cases? Meaning cases without bullets in them.

 

[wholman]

No

Me either Stan. My Gempro says 0.010

Zero magnification, prone with a sling, with ammo made on a progressive. 243. 105 Hybrid. N140.

"John full-length sizes his match brass every time using a Whidden click-adjustable sizing die. The powder charge is dispensed with single-kernel precision using an Auto-Trickler and lab-grade force restoration scale. The process is completed on a Dillon XL 650 to produce more ammo in less time."

Wow.

 

[rafale]

Not N140 but N160 for the 243 !

 

[urbanrifleman]

Oh I am stupid. That is what I meant

 

[steve123]

Nope. I suppose I'd start there if I had to diagnose a run out problem.

Tom

Okay, I just wanted to know how extreme you guys get on brass prep, run out and what the most important aspects of what it entails to shoot the smallest groups at long range.

Thanks again

You do realize that is a much reduced scale model of the real target, right?

Still awesome shooting, but that ain't a LR target...

 

[urbanrifleman]

No. I did not.

 

[Stan Taylor]

I did a little research an what it would take to load to the kernel I don't have to worry about trying to be a champion contender I cant foresee the cost of those eleborate set of scales so I will just try an be at least competitive.

 

[DJSBRS]

Help me out here guys. How much does one kernel of powder increase or decrease the FPS or cup pressure on a Dasher, 260, 284 and 300 WSM? How can one consistently measure it and adjust accordingly on paper at what distance? At what point is it a moot point where there is no juice from the squeeze?

Is this like picking fly crap out of pepper?

Dj I would also like to see the same answers.

mute point

"moot point"

Thank you kindly!
