I'm with Ned Ludd. I have the mentality that every round down the pipe is one more round that puts wear on the barrel. I will FF new brass at local score matches since we have a lot of one yardage matches up here in Maine, but I ALMOST learned the hard way not to FF new brass at a National Event. To make a long story short I fired match one FF new brass at 200 yards and only shot a 50-1X. I said to myself you better use fired cases the rest of the match with I did and fired a 50-4x on match 2 and 3 straight 50-3x's which was good for 1st place with a 250-14X's. NEVER USE NEW BRASS AT AN IMPORTANT MATCH, NEVER!
