Is it common for the speed of a bullit to slow down as the barrel gets more fouled as you shoot? I started my first string of 5 and averaged 2990fps with my .243,115 Dtacs, 2 strings later I was averaging 2960 and 2 strings after that I was averaging 2930.
 
Re: Velocity

Were you letting the barrell cool down between strings? As the barrel heats up and expands your velocities will drop a little. At least that's been y experience.
