Well--I am reading.
I do communicate so poorly.
I will post the question differently.
Without consideration of wanting to experiment I follow the manuals.
What, in the composition of a primer, is the primary concern for the bullet and powder being used---is it pressure or complete burning of the powder.
I understand that the faster powder is burned the more pressure it builds.
Dane Burns is a Gunsmith of some good reputation and considered, by most, to be a real authority on the 9x23 and the reloading and development of this cartridge.
I follow his advice.
The primer does more than ignite powder--it directs/starts a controlled explosion.
The critical issues--even the low powered .45--is what I am trying to understand.
I am not trying to re-invent a wheel.
Blessings
