Just fired some loads thru the 30-06,Pacnor barrel Remington 700 jewell trigger all the good stuff.It does have the light wt firing pin with the strong spring. I've been shooting this same load for a long time/ 12 plus years. 56.0 gr of H4350, Nosler ballistic tips / partitions with remington 9 1/2 primers. Still shoots good but soots the barrel after every shot. Checked OAL the die didn't slip, same powder lot only change, is primer lot or bullet lots. Carbon problem, to lightly loaded for the new primer lot? HELP
