Do you weight sort primers?

[Bc'z]

You can certainly make a factory gun shoot, if it will let you. You wont find an argument from me on that. My first year back into it I shot a savage 6br factory gun in short range ground hog matches, (200-500) and I did everything I could to make it shoot better. I was on the heels of the full blown custom guys for the aggregate of the season, and some of them are very good shooters. I root for the underdogs and people that find the ways to make things work better. And maybe you don't even want to shoot competitively, maybe you just want a very accurate rifle. There is absolutely nothing wrong with that.

Depending on the distance you shoot, the discipline you're shooting, the goals you have, and how competitive you want to be, will decide how much you need to do. Can you afford to have one shot (or more) come out of your group at 1,000 and open it up to a 10"er? (And in conditions that you should have shot a 4-5"er) Not if you're going for the aggregate. But then again, maybe you're comfortable with having that happen.

I dont mean any of that directly towards "you" and only used that as person I am asking those hypothetical questions to. We all have our limitations, expectations and desires in this game. Thats what brings most of us together, and even makes us butt heads from time to time.

I feel ya,and appreciate the way you put it to words.

I dont post much but this is a question I'm asked a good bit so here is my 2 cents.

I weigh every one!

If you dont weigh your primers then what your saying to your self is that when your loading your record rounds your ok taking 1 primer from every pile of a weight sorted set. From the very lightest to the heaviest.

The thought of seeing the ops pile of primers all nicely layed out and me loading my record rounds and by just pulling each primer from any random pile is somthing I would never never do.

Does it help? Who knows but one thing I believe as fact is my record rounds are as close as possible to being identical. Primers are a part of the whole. It doesnt take that long. Why not?

For those that don't weigh primer.. hope I draw you in my relay!

No I don't.

I was wondering... have you tried annealing your primers?

I'm not sure if it that has been tested yet? Let us know how it works out.

I have a friend who got things out of sequence when he was annealing cases. He ended up having to explain to his wife what all the noise was and he had to pull a couple cases out of the ceiling.

I think I’ll pass on that test thanks.

So many variables in reloading what's another one . Thumbless people make better bench shooters .

Yup! After weight sorting them, I then sort them by "cup height" (being careful not to include the anvil in the measurement), and then I mike the cup diameters and sort them by diameter. Occasionally, I will perform a 12-inch drop test of 100 loose primers on to the top of my reloading bench; those landing anvil-up go to one pile, cup-up to another provided I can find them...……………………………….……….

NO I DON'T!! IMO, weight sorting primers makes just about as much sense as weight sorting freshly loaded cartridges. (Yet, I've had shooting friends that sorted their loaded cartridges.)

Great Post my Friend!
You keep stacking up the wood and maybe the others will catch on, especially the 12" drop test. LOVE IT !

One of our fellow shooters says that he even checks them for concentricity!

 

[INTJ]

Even in LR BR, with average to poor conditions average loading practices are fine. Given most of our shooting is in average conditions people can get away with a lot and confirm their own biases.

However, the person willing to weigh primers and sort bullets three different ways is likely doing everything they can to shoot as accurately as possible, and doing everything to the best of your ability is what wins matches.

BTW, .3 moa at 100-200 yds in a 6 mm LR BR rifle is evidence the load still needs further tuning.

So this is what 1,000 Federal 205M primers look like after you weight sort them to .001 Grams.

No, I didn't count each group but you can see a very nice bell curve. The total variation was .008 Grams.

The average weight of the cup and anvil from some prior testing I did was .215 Grams so the priming compound should vary from 0.030G to 0.022G, a 36% variation.

My question is do you weight sort primers and why or why not?

I'm sure some of you are wondering, it took 2 hours and 15 minutes to sort them.

Dave.

OMG...you guys are really in the weeds now. I think I'll change the air in my spare tire while you sort primers by weight! LOL
