Did that Hodgdon test crimp there cases ? Will a good amount of crimp stop any primer unseating of the bullet ? Which intern will give a result more like your quick loads data ?

My post about testing pressures with different seating depths was partially to point out that with any question posted about "short seating" there are several/many warnings "pressures will rise to dangerous points". While I agree in theory that this can happen, I believe 99% of those answers are just from what someone read on a forum (parroting), and very few facts are offered...

Undertand. The primer unseating phenomenon throws a monkey wrench into what is supposed to happen in principle. I know people who fired a pistol bullet that had been set way back in the case. I wouldn't, but they got away with it.
MG, I think with any round that is predominantly used in revolvers, you can assume some degree of crimp is standard to prevent bullet back-out in cylinders. But no, it doesn't seem strong enough to affect the primer unseating, as the Hodgdon example shows, though it should raise start pressure some.
