DezIWezI, I do not have a slide type pistol that will not seat primers, scary part, if the case is sit on the base, it will not sit straight and if in the upright position and the powder trickles down through the flash hole the area ahead of the primer may be filled with powder leaving no room for the primer to move (seat) when the slide chambers a round, this, in theory, could cause a slam fire.
Just a caution: Another consideration, a primer that fires without powder may not be audible and will not cycle the slice, this does not mean the bullet cleared the barrel, scary part, the primer can launch a bullet into the barrel enough to allow another round to chamber then if that round functions as designed, the first bullet becomes an obstruction and the weight of the bullet traveling down the barrel doubles, it is easier for the pistol to come apart than it is to push both bullets down the barrel.
A revolver in good shape should not have enough room to tolerate unseated primers, when loading a magazine for a slide action the rounds are feed one at a time, this is the last chance to check for poorly seated primers, the time before that is when the bullet is sit on a flat surface, the first opportunity comes with a well designed shell holder in the primer seating tool, most shell holders have a slot that protects the hand loader from him/her self, I have semi auto loader shell holders that don't have a slot for the primers and the shell holder does not have a lot of slack meaning it is not easy to remove a case from the priming tool with a high primer, BUT! persistence sometimes prevails, as indicated by the number of cases loaded and chambered with 'high primers'.
Again: a friend, while at a range, tried to assist a shooter with a new rifle and new ammo, out of 20 rounds of R=P 30/06 fired, 5 did not fire and were hit twice in one rifle and 2 more times in another rifle, he came over, we took the rounds apart, checked componets, were were impressed with the condition of the 15 fired rounds and the condition of the rounds that did not fire, we removed the primers, bullets and powder, weighed each and reassembled the 5 rounds without powder and bulleet then chambered each one and fired the primers in a M1917, all 5 primers worked as designed even though each had been struck at least 4 times. From the beginning I thought they should have contacted Remington and Ruger, seems they were happier bashing Remington ammo.
