i have a mark7 650 pro
Lee seating and crimp die
125gr gallant coated lead bullet
mixed cleaned range brass
my target is 1.165 and most come in a 1.163-1.165 but then I get some that are 1.171 and its absolutely driving me nuts..... 29 round test batch 5 were too long at the 1.17 mark....
ive checked shell plate, cleaned the die, readjusted the die, measured a handful of projectiles and they all are within .003
Any suggestions?
