Range Report (repost from another thread)
I sure could use some help with interpreting the data. Was hoping some better groups to launch this investigation into Bart's 80g.
The gun:
26" Heavy Varmint Criterion 1:10 6mmBR .265" neck, .02" FB.
6600 ft elevation
IMR8208 with 205m primers
Jam=.012"
R700 trued action; Jewel Trigger Sightron 8-32x
Wind 4-5, steady on at 90 degrees from the left.
41 degrees 1020mmHg
The sighters where 31.4g, touching.
SD was single digits from 31.4 to 32.2 (basicall 3 and 4). I'm happy with that!
Best groups, in the 4s! BARF! 31.6 to 32.2 (4x sighters measured .257")
Overall look at speed is a steady incline . . . not seeing any flatting of speeds between groups to represent a node.
Question: Seems to be some odd looking holes in my target. Not quite keyholing. I do have a nice solid piece of plastic sigh (like those political signs you see on street corners).
Is this worth pursuing? should I scrape IMR 8208 and try some N125? Perhaps reload with 450s? Try touching the lands like I did with the sighters?
Any thoughts and your help is most appreciated.
