[QUOTE="3sixbits, post: 66413, member: 3661"] Let's look at what is going on with the case durning firing to answer that question. The loaded round upon firing is expanding and moving in all directions within the freedom of the chamber and the breech seal ( bolt, breech block) alow. At the time this obdurating is going on the obstruction in the bore is moving away from the ctg. case and moving down the bore, the pressure is steady even though the fluid mass has been ejected in to the bore, pressure is still at work causing some setback that is felt on the web of the case head that is against the breech block. This can be measured as case head expansion. Well this set back in the primer pocket is what you are removing using your primer pocket uniformer. You are doing the correct thing because you are making the depth consistent for the primer. By seating the primers to just touch the anvil and not crushing the pellet, you've given the ctg the best you can help in the ignition department. Setting-up your pocket uniformer tool is a matter of just making a clean-up cut after the first firing (no deeper)this setting will remain the same for all other reloads for these cases. You will notice that sometimes you seem to cut more than others as you progress through out the life of the case. Never fear this is quit normal. I don't see where you can be going wrong, unless it would be on the set-up for the first reload by over cutting the pockets to deep. [img]/ubbthreads/images/graemlins/wink.gif[/img] [/QUOTE]
