Velocity inconsistancy
I'm having trouble getting my velocity to be consistant. I loaded 50 rds today with 168gr bthp on top of 1680 powder. I checked several rounds and was within a 1/10th gain on my powder charge. I had up 347fps extreme spread. I'm using a Dillon 550 and Reminton 223 brass. I'm loading for subsonic. Do I need to trickle charge my powder for each round?
