Thanks HawkI, the .223 loads I was speaking of would flatten the primer, blow a hole in them, and smoke would roll out the back of the bolt. They would actually kick a little bit and they shot high compared to the previous loads we had shot that day. We only fired a couple of them and then decided to switch to another box. Problem was that the trigger would no longer function. So you all, hopefully, can understand my apprehension. I am just learning to reload though and to waste his knowledge would be a shame.
