[QUOTE="MajorSpittle, post: 1560146, member: 53101"] It does make sense that if the Primer is smaller then the pocket that the primer cup would be stretched at the base to fill the primer pocket and this could cause the primer to rupture there like what happened to me. But the question is: Was the Primer manufactured too small? Was the Primer manufactured with too thin of material? Was the Primer manufactured with too soft of material? Was the Primer Pocket on the Brass too large? This is my take away from this experience: I would urge people to pay close attention to primers going in too loosely. All my CCI200 primers went into the brass with a normal amount of pressure. The WLR was a much lighter pressure then normal. I did verify they were not moving after I seated the primer and then made the poor decision that the difference in seating tension was "normal" for WLR primers. I will be measuring the primers and the primer pockets on my brass now and try to figure out what the issue was. I have seen no indication of excess pressure in the other rounds fired and I am under book max by 1.5 grains and significantly under book max velocity and lower than book velocity for my load (I have a larger COAL than book on my rounds but am still well short of touching the lands).
