rear sight issues solved today

[chaneylake]

the Hadley disc just will not stay tight, she must have fell down the canyon

I sent 10 down range to the 300 yard target in the swirling winds today, I checked sight after 5th round and the settings had moved.

I reset the sight on Hadley, sent 5 more down range and she had moved again

I had her 4 fingers tight, she is still letting the settings move

my cure, I removed the Hadley and screwed in the disc that came with the sight. I then sent 10 down range to the 300 yard target in the swirling 10-12 mph winds today

here is the result, 10 shots, 300 yards, 10 inch black circle
