For those who sort primers....

[ORjeff]

Back to the original question....I use the plastic containers/lids that restaurants use for sauces in a to go order. Raid your local salad bar. I'm not worried about safety, they don't leave the shop.

I'm just starting to do this to see if it will give me better results, sorting to +/- .00025 grams because I can. Fun fact...the distribution is very gaussian. Unfortunately that means that I need to sort a lot of primers to get enough for a shoot and that's only from those weights around the mean. The heavy and light ones will go back into storage for after the apocalypse.

Would some please explain to this old man why one sorts and weighs primers?

Is the weight in the anvil? The primer mix? The cup? Does it matter? Can someone show me "on the target" that it matters? Inquiring minds want to know. We as shooters tend to complicate things as much as we can

There have been several examples on AS of the heaviest primers shot against the lightest primers at longer range some show a separate point of impact from one to the other along with fps variations.
At short range it may not be of any significance so it’s just a matter of desire to not leave free accuracy sitting in the reloading room for the three seconds per primer it takes to weight sort.
Small groups have been shot without sorting or cleaning pockets also, so take your pick and have conviction in what you’re doing.

Is the same group of primers weighed after firing to determine any difference in weight was in the primer material and not the primer body itself? Not sure how to clearly word it but weighing only prior to firing is incomplete and less valuable data it would seem.

Never have weight sorted primers. I have sorted Federal Match by color or the way the looked in the past. The compound being more red or green. I shoot Highpower Long Range. Does it help? Maybe. A very well known Highpower shooter once told me of sorting brass and bullets was to look for the outliers, what may put you in the 9 ring or worse. Overall it didn’t really matter but once sorted, why mix them back up. I’ve found off weight bullets in well known brands. It happens.
