I was loading some .223 Hornady FMJ-BT last night and I notice that when I use the COAL recommended in the manual for a 55gr. Nosler BT, I was a bit short of the cannelure on the Hornady bullet I was using. How important is it to maintain a COAL as directed in the manual, versus seating the bullet to the cannelure?
I've only been reloading a few years and the other cannelured bullets I have used have been .375 H&H or .44mag and seating to the cannelure was within a couple hundreths of the COAL pulished so I never worried about it, in this case it was more like .05 difference, is this significnat?
Thanks in advance for you thoughts!
