Weighing primers !

[Jefferson]

a missed winflag change of ANY SIGNIFICANCE is way more important

also if you weigh primers and things go wonky in the line odes YOUR not my mind wander or wonder about,

golly what could that have been, a bad case, a bad bullet, a bat primer weight

and the loons in short range benchrest blame it on

MY LOAD BLEW UP to push the blame on that rather than bad bag handling or missing or misreading a condition

or even being a second or two late in reading flags or the wind is picking up a little faster than first thought

so many things to go wrong we never or at least you never run out of excuses

it is a one hole rifle IF I DO MY PART

gotta take a nap as part of my mental conditioning in order to,not make a mental mistake on the,line next week, either that or re-sort primers twice

keep smiling boys and girls life is fun, shooting is exhilarating

 

[JFrank]

I could but in the last my similar testing proved no conclusive results to any standard deviation nor in any material group size difference

no need for me to repeat a test from 5 years ago expecting different results as that is just a common definition of stupidity

so you are saying you are too lazy to do it and want someone else to?

I’m not trying to convince anyone, I don’t recall the OP trying either. I test or sort for my own interest and do not crap on others who do or do not.

 

[Jefferson]

nobody is crapping on them

if my opinion is it is not significant then bugger off

this is a forum,where knowledge should reign supreme

sort your damm primers I will be found on the range improving my skills
‘or in the house with a bench set up improving my style

gooy if I told you to practise with inert ammo in the dark loading and cycling rounds and you disagreed then we agree to disagee

dont be so darn childish and suggest anybody is crapping on anybody else
dnot crap on me either.

When contemplating errors that can cause you to miss a point or miss several points during the course of a match, I am sure what you had for breakfast is at least 100 times more important than what your primers weigh. How many points are lost in matches over the entire country due to gastric distress?

Save your negativity for someone who’s interested in listening to it, I prefer to focus on positive input.

I had that this morning..... Shot some really chity groups @ palmetto !
After lunch it got better and so did my groups...
I think you're on to something !

 

[Dimner]

The nay sayers could do their own testing and post their own results just as easily.

Standard logic says..... The people saying Method A = Better B, are the ones that should be providing documented proof.

We don't see scientific journals with papers showing that marshmallows will not cure cancer.

Anyway, I lean towards the side of, it is worth the time if one can shoot the difference. Many shooters are that good. I'm not. .... yet (hopefully)

 

[Liven The Dream]

Most fall in 3.60 - 3.73...... 98%
Then ive had 3.3, - 3.5, & 3.8, 3.9

I do not have a clue where the weight difference is from..... Not important, they get culled

You need to remove the anvils only way to find the true difference.. page 17 thrid paragraph.
Your Welcome

I assume that the culled ones are not just thrown away but perhaps sold on to your mates at the range that cannot buy any primers locally...???

Screw that !! I use them for my case forming and foulers......LOL

The above video from Witch Doctor is a good one. I did my personal
testing at 500 yards since at the time I was shooting steel at Ridgway
Pa, out too 1000 yards. From 6:00 to 8:00 am, it's normally dead calm,
at the Spartansburg Pa. range. Note, I shoot LRPs where the dispersion's
can be greater, in primer charge weight.

Here is my latest sort. The BR2's went from 5.38 grs to 5.18 grs. That's
a difference of 2/10th. We all know what 2/10th more or less of powder
will do to a tune. Now one thing to think about is the greater energy
That a priming compound has over the powder it is lighting off. It's all
about the pressure. 2/10th's more priming charge can and will increase
pressure. Change the pressure unevenly will change your target.

Everything in the 5.30 gr range and up, (maybe 60 out of a thousand)
went towards fire forming. Everything else is sorted for matches. The
5.24 gr batch was the largest with just under 300 repackaged. These
are put away for guess where ??

Primers sorted, primer pockets uniformed, flash holes deburred, brass primed and sorted by primer seating depth so to continue my severe case of OCD I checked internal case capacity and picked 100 cases between 26.90 and 27.00 for the upcoming match
Now it’s time to trim and point already sorted bullets and run them on Genie to eliminate any outliers, I don’t think all that is necessary but like the saying goes “I do about 20 things in my reloading process…..Likey only 10 of them actually make a difference. I just don’t know which 10 “

I'm excited to see how it turns out. You setup a very nice test plan.

 

[quest450]

Yeah I'm looking forward to see how it goes, paper doesn't lie
It's not really a test, it is my reloading process that I've developed and I've been testing for a while.

 

[4xforfun]

I perform 14 different precise and exacting steps to my loading procedures on each and every round loaded. Only 4 of them ACTUALLY do any good.

I have absolutely no idea which 4 that is.

Time for some testing, then. 14 different experiments designed to isolate 14 different variables ought to do it.

 

[Dr. Matt]

Is this an odd distribution or a glitch with the scale? I'm using a Hornady scale and sorted 200 culling the extremes

 

[Rocketvapor]

What were your extremes?
You gonna shoot them as a test?

 

[Dr. Matt]

Yes. I like testing extremes to see if there is a difference. They ranged from 3.41 to 3.68 Remington 7.5 SRP Benchrest

 

[Rocketvapor]

Weigh them before and after firing.
Velocity and POI at a range, preferably greater than 100yds to show verticle stinging.
