Once again guys I apologize for blowing up the forum but I ran into something tonight and need some help.
I setup my RCBS 223rem dies to just set the shoulder back a few thousands on my rifle which has a tight chamber. I have another rifle with a loose chamber and looks like I got some of its brass mixed up. I sized the cases with the die setup for the tight chamber and when loading a couple empty cases in the rifle to make sure they fit right its very hard to close the bolt. I know this means the headspace is tight but could too tight cause pressure issues? it seems these LC 08 cases don't like to be sized cause I ran them through the sizer again and still a lot of resistance closing the bolt. My lake city 07 I usually run in the gun chambers fine without resistance.
