Yep....that would do it. Means there was some pretty excessive jump going on. The GP-100 is not what I would consider a lightweight gun for the caliber, but the PMC ammo, going by published velocity, is pretty stout. Can you see the roll crimp? Many times with factory ammo, the roll crimp looks more like a taper crimp.The gun jammed and I could not cock it
