I have the RCBS Universal hand primer. It works great for everything EXCEPT 45 COLT/454 CASULL(that really small rim)
Anyway the other night I swapped over from Large primers to Small primers.
The first 3 cases had HIGH primers! I have NEVER experienced this.
It was then that I remembered that I didn't tighten down the 4 hex head bolts on top!!!
Once I tightened them correctly, she ran like a top!
I've probably primed 50K and this was a first.
Hope this helps!
