3 groups 300 yards
far left and middle groups cases were sized with a bushing die, annealed on Anealeeze, primers seated .003 below case head, necks lubed with Imperial graphite, powder measured at plus or minus .02 grains, bullets seated and checked for less than .001 runout. Five sighters were shot on a seperate target
far right group same except no annealing, no case lube and no checking for runout
Velocity consistency was horrible on all three groups but at 300 it did not seem to matter. I was watching through a spotting scope and higher velocity shots were hitting lower on the far right group. Barrel harmonics?
Anyway I found out how to prevent my flyers, so eating some crow about annealing and overly anal case prep is well worth it. back when I was firsdt testing annealing and neck lubes any advantages were getting lost in th enoise of my poor shooting. Seems like now my shooting technique has advanced to the point where I can see a difference
Oh and the middle group was shot using the horizontal crosshair centered on the green dots and the vertical crosshair centered on the sighter bull which was above this target. I was only planning on shooting two groups but figured the range was going to be hot for a while so I improvised
