Thank youI like the ambition, but I would not continue to bounce around on yardage you will chase your tail. pick a yardage that you intend to compete at all primers most all primers are tunable the goal is to streamline results sooner than later. often once you get a gun mostly cleaned up on one primer very often there will be another that just edges it out that's what your looking for not a complete re-build unless one just refuses to give respectable targets anywhere then completely rebuild if necessary. primers can be a slight fine tune to the good or a course chance to the bad by this point a guy is usually fine tuning you can not I repeat you can not do a fine adjust at multiple yardages, there is more to it than that. if your a position shooter with multiple target sets to deal with I Shawn Williams implement additional procedures
to draw the best out of multiple targets.
