If anyone has fired the sierra match king .30 cal bullets in 168, 175, and 180 grain from a .308 winchester using the same gun and the other components were all the same I would like to know what velocities they were traveling at for your most accurate powder charge.
I am considering changing from a 168 gr to either a 175 or 180 and wanted to mess around with the ballistic charts using real world velocities that I could compare to my 168 gr loading.
