Flash

When you open the flash hole the primer will not back out when fired. That may be it or they are shooting wax bullets with the primer as the charge. Or blanks. Hard to tell from your description.

I have used 45colt RNFP bullets since the sport started without flaw in my 73.

 

Me, too, Chance. At least since I started!

+1 on that.

I never sign out. It shows I am still signed in just not allowed to visit this community...

 

In fact, when this "error" message is there it will not allow me to sign out or access anything

You may just need to sign in, I see that message when for some reason I am not signed in anymore.

I have pulled hundreds of "mistakes"over the years with an impact puller and I have always reused the primer if it was seated correctly without any problems.  Your experience my be different.
