of light primers verses heavy
speed on left is lab-radar on right is speed at 900 m on silver mountain electronic targets
only Fed Gold Match for me they ere not weighed

Nailed it !Since the primers are NOT a single component , I don't see the benefit .
You can't disassemble the cup ,anvil ,powder slurry , and disc . Sooo , which one will be the offending weight difference?
Just pointing out the problem with weighing the component. It's like weighing the entire cartridge.Not disagreeing with some of the assumptions above, however I will argue, pondering and then fleshing out the issue is a good thing. Vetting the issue on this site is good to get other opinions and help with writing the “problem statement”.
I believe testing is the fun stuff, after framing it up correctly.
I see lots of criticism for not framing “it” up correctly and not a lot of help to @manitou210
@Ned Ludd gave it a good go, thanks for that.
If I had a scale accurate enough, I would be testing this myself. I may anyway, and see how it goes.
I expect a few targets shot round robin with the heaviest and lightest primers at distance will separate the fly sh_t from the pepper if it has any merit.
Suggestions welcome
Edit
Is the 1s 64 Sartorius accurate enough to separate the primers? Maybe I will invest in a new scale and have some fun.

No argument, what so ever.Just pointing out the problem with weighing the component. It's like weighing the entire cartridge.

must be tested at 1000yds for any real conclusion IMHO
g.. i thought the same thing.
i was proven wrong. the consistency of the cup anvil and sealant,
makes the priming compound "weighable".
results seen on targets at 1000.
( no it is not perfect but it is measurable on targets)
does anyone on this thread shoot competiton br at 1000 ?
if not it is just noise
It has been stated in other threads here that the weight of the primer anvils/cups are extremely uniform. Whether you actually believe that or not is one thing, but if true, it means it would be relatively easy to determine weight difference between the primers' internal combustible materials with an accurate analytical balance.
I have never personally disassembled spent primers in order to clean and then weight the anvils and cups. I don't want to do this. I have never personally weighed primers in an attempt to sort them into sub-groups of different brisance. I don't want to do this. Other than comparing primers from different manufacturers to see if one brand gives lower ES with a given load, I have never personally carried out any of these kinds of primer experiments. I don't want to do this.
The reason I don't want to do this is that if sorting primers by weight turns out to have a real and statistically significant affect on brisance, and therefore velocity, I will then be compelled to add sorting primers by weight to the sickeningly long list of other tedious and painful sh*t I already do in the quest for consistent handloads. I find I really seem to stay much happier, more satisfied, and emotionally whole by letting someone else carry out these experiments and reading about them here, after which I can then critique their approaches and results with minimal effort.
