Anyone ever try one? For picking a 1000 Yard load?
Did my first one yesterday, using sharpie-marked bullets to mark holes. No need for a forward observer, or pits...spotter behind me only confirmed that the shots hit the paper, so woth good conditions, one can do this alone...
Shot 2 shots per charge, round robin,sort of) low->high; low->high so fouling/heat conditions were evened out.
sited in low on a tall target with the lowest load, and the highest load,100fps faster) ended up about 3feet higher than the slowest)
This was with a 284/180berger/H4831SC .3gn increments 54.7-56.5gns,2780-2880fps)
55.3 and 55.6,4 shots) went into 1.5" vertical at 1020yds. The others climbed predictably up the paper. velocities:2808, 2809, 2809, 2818
Funny thing though...the whole group seemed to expand horizontally approaching the cluster, then narrowed again at the top end...basically a vertical diamond shape if you outlined everything.
I plan to try a 10-shot group at 55.5 and see what happens. Ideally, this should give me a pretty flat group, but who knows...
Thoughts? Anyone ever try this before?
