Yesterday I loaded up 30 rounds for my 6BRX and went to the range to shoot at 600 yards. I took my Yamaha Rhino so I could use it to hang targets and put up wind flags. The battery was dead so I had to carry a jump box to start it each time. I unloaded all my gear on to the bench and prepared to shoot on this beautiful day. I loaded a round into the chamber closed the bolt and pulled the trigger; nothing happened. Same procedure again with same results. Then it occurred to me that I failed to expand the necks to create a false shoulder for fireforming. Needless to say I was not happy. Don't you love these cartridges with all their idiosyncrasies.
