Weighing primers ..bored...

[JMayo]

Ok, talk of weighing primers made me wonder what kind of spread there would be. So I started weighing and just like most of what I do I became obsessive.
Cci 450's
3.500 - 3.756
So it's not so much about the ones in the middle. It's about the ones on the ends. (culls) I shoot bench rest only.

I'm using a scale that WILL weigh accurately with in .002

Now shoot the extremes and let us know if there IS actually a difference...

 

[Mulligan]

That’s awesome!
It would be good to find out at what distance the sort of attention to detail really matters. The SR benchrest guys have alredy proved it doesn’t matter at short range.

I think more like.... see if my groups get more consistent without them.
They'll be foulers.

 

[Puzzaz01]

Yeh.... I think I'll watch this thread and see how it pans out.

You're foolin with us right?

My hypothesis is that the weight differential in the cup/anvil/primer compound assembly does not consistently correlate to the weight of the primer compound by itself, which is what I further hypothesize to be the variable correlated to consistent accuracy. I look forward to your test results to potentially prove me wrong!

Everyone has their limit as to what they will do to achieve Handloaded Nirvana. This thread is mine. No way I am doing that.

Id bet the anvils and cups are closer to perfect than you think. Ive weighed them after being fired- pop the anvil off and scrape the cup with a little screwdriver. I wont do this with live ones btw so please dont try

@Dusty Stevens
What kid of difference did you see cleaned vs unclean? Were they consistent?

That was a long time ago. I remember weighing them, getting a difference, shooting the outliers in the same hole, then weighing the cups and anvils seeing no difference so i figure it had to be the compound was the only diff. This was 205m in the white boxes from the early 2000 era

I'm comfortably retired and have a lot of "me" time. But, I pray I never get to the point of weighing primers!! But, I have been known to overly fret on turning necks! Wait a minute...Primers vs. necks. I need another glass of moonshine.

When you shoot the extremes tell us what yardage you shot at (maybe 600 at least )

I have a large magnifying glass on an articulating arm with a built in light. I use the tray from an old primer seater to shake all the primers face up then inspect them for any that look out of place and separate them. This only takes a min. of my time and makes me feel like i did something. VERY rarely i find one or 2 to cull....

If I must weight, here is how I do it: Take one 100-primer box, empty the primers onto a scale tray, and weight them. Then divide that weight by 100 to get average primer weight. Less boring, what!

Also more accurate for the average.

 

[dannyjbiggs]

Do you then go through and separate hi and low for sighter foulers?

No. But, sometimes I will do this for each 100-box in a 5,000-case, and arrange the boxes in a shooting order...low average primer weight up to the highest.

On a shelf above my loading bench are about 3,000 primers left over from a case of the original "Russian Primers", KVB-7, Lot # 3-03. These particular primers were weight-sorted by me last century (I think, whatever, it was a long time ago!), weighing one at a time, and sorted by 100-box. (I still shoot out of them time to time.) After that tedious sort, I tested using 10-shot groups from the bench...comparing an un-weight sorted primer sample with sorted primers, being sure to take a sample out of the heaviest box. I proved out that I had wasted my time.

Well, you know those times you are really bored, you look over at the wife or gf and say "hey baby" and give her the nod ....
If you're unmarried/alone as I am ...
well I won't go there.....
So weighing primers is a way to spend time other than ...... (fill in the blank !)
Lmao !

 

[corning]

Weighing primers...sounds like a retirement job to me.

Personally, I wouldn't go to that extreme. In the grand scheme of things, I focus more on the overall weight of the completely loaded cartridge. My tolerance allows me to accept 1 gr weight variation. My loaded rounds, with Winchester brass, and 155's will 370 some odd grains, +/- 1.

I can understand this "obsession" for bench rest, or maybe f-open, but for sling shooting, or hunting, no.

Never even heard of weighing primers till now. Right, wrong, dumb, smart, whatever: I think it’s cool when someone thinks outside the box.
