Nothing ! The possibility of a detonation would not change.
It's just that there could possibly be more damage if it were to happen in a charged case... The same reason Lee used to say to only put so many primers in their auto prime... In case of a mass detonation, they wanted to keep it to a minimum number of primers... The manuals never said it was a "safe" step... They always did and probably always will advise to take precautions when using primers...
Exactly!! But thats not how they make it sound, and it certainly is not how people take it. They think it is dangerous to seat high primers because of a "higher possibility" of it detonating, which is just not true.
You know i may actually have to run some tests of seeing how much a primer can actually take before it detonates. They are not the fragile little things people seem to think they are. Hmm...i'm already thinking of some ideas.....
I just wanted to clear up that there is not a higher possibility of a primer detonating by trying to reseat it(as people seem to think).
