Gentlemen,
I would like to know more about the make up of a primer?
I understand they have a cup, substance and anvil, but what is this all about?
A std vs match vs magnum?
Is a magn primer hotter in burn? or does it provide a larger flash? or a longer burn?
when is a standard primer not sufficent?
how do they differ?

Some weigh primers, what are they looking at?
has anyone worked with primers being manufactured, weighed the parts to see if they vary?

German Salazar is a good read. Some of the very best work on the subject.

than a good read, he should be a MANDATORY read. He is maybe the only one who has ever done an unbiased study on primers, top to bottom, soup to nuts. Take the time to search out every dreg of info you can from him.
 
Thanks for your replys
Will get on and do some reading
Good shooting!

Some good reading, still have some questions

Thanks for the heads up, that was a great read!
There is some excellent articles, with plenty to engage and challenge the mind.
if i may ask some questions, and correct me if i read this wrong.
Primer cups vary in thickness, got that
Primer seating and pressure applied is important.
And the coating can be damaged easily . A good one to think about.
I got confused by the photos, as i could not see how they where different? apart from the appearance of the flame?

The primer coating weighs about 0.5gn? If i read it correctly,
so when you weigh primers, what weight increments do you batch them into?
I am assuming the burn column and intensity is varied by the amount of coating? more coating/ more heat?
Does this variation give you potentially a greater ES? or have some other effect?

For answers about weighing primers, you probably need to ask the 1,000 yard shooters. I don't know of any 1-300 yd shooters that weigh them. As to what you should be looking at in the pictures that you mentioned, it is the differences in the appearance of the flames. As to primers being easy to damage, with ordinary care, this is not a problem. Targets will tell you what primers work the best for a particular situation, beyond that, I wouldn't get too excited. There are a lot of other details that you may need to pay more attention to. One more thing, I think that most of us seat primers by feel.
