I have the same problem with spot targets. My groups open up a good bit with the blue three spots and even more with the bright red and yellow targets. I like to pick out a small blemish on the target and shoot for that. I can stack them all day long like this.
"pick a hair and shoot for it."
That's the way that I like to practice. After all, a deer don't have big bulls eyes painted on them do they
?
