I can sight in my rifles and do really well with pistols at 25 yards, but when I get ought to 100 yards, I waver back and forth. I try for the quickest shot i can get so I can cut the waver, but still it's there. Any cure that you have heard of? I can use a tree for support and still get the wave. No fun. I still want to kill those coyotes that come after my goats and then a deer this fall. Thanks for the help.
