I am trying to load out my 6mmx45 rounds and I cannot make my OAL any smaller than 2.275 and I have tried to use a different locking ring off an RCBS die, and I cant make it any smaller. Only thing I can think is I am using an RCBS shellholder? I am using this ammo through an AR and obviously this is an issue. The top adjuster wont go down any further and I have the die touching the shellholder almost to the point of camming over. I am lost.....do I need to buy a Redding Shellholder to get the extra .020?
