When I first got into progressive loading, I wasn't paying enough attention and ran out of primers. That one was pretty clear pretty fast when my RCBS Ammomaster started getting really, really dirty. Just to prove I'm a slow learner, I ran out of powder in some 9mm that popped, pushed the cast 115 FP into the barrel. Did you know that the little springy case holder in inertial bullet pullers have a finite life? I found that out. After I wasted the second puller I figured out to use a regular shell holder. I also bought a press mounted puller.
OP, how cold was it when you were shooting? Cold enough to cause any lubrication in the gun to thicken up, causing weak primer strikes?
