Brad prompted me to talk about the firing sequence of a cartridge.
so i'll start it out as a discussion of each sequence when pulling the trigger.
this should help us visualize what we are manipulation when we change things in a load.
the first thing we should discuss is primer ignition and the brisance level of the primer and what it does to the powder and the case itself.
next it should be powder burn rate.
then pressure on the case.
then how the bullet can influence both the burn rate and pressure.
we should also discuss how the case swells to fill the chamber.
and finally how case shape influences pressure/burn rate/and gas movement within the case.
lets talk about the primer.
we know that different primers have different brisance levels, but what exactly does this mean [and mean to you]
what exactly does the primer do to the powder when it's lit off?
and why would a change from one formulation to another make a difference on target.
