I just pulled out my 550B toolhead that was set up for my .223 loading and checked the charge weight before loading. The powder measure has sat, untouched for over a year, (never changed the charge setting) as the RL15 powder has since last loading for my AR. Now the powder charge is reading .3 grns lighter than it was last time. Should I load "as-is", or turn it up .3 grns to meet my preferred 24.3 grns under a 69 SMK load? Thanks-
