here is what I do not understand

[chaneylake]

10 shots @ 200 yds
damp patch wrapped around nylon brush, followed by 2 damp patches

rounds 1-6, right group, measure 2.9 inches @ 200 yards, the group is finished out with the other 4 shots to the left

I felt good with each shot

what gives



I then moved to my first ever 300 yard target and once I quit messing with the sights, felt pretty good, bottom group is 6 inches
