Nah he is too old to shoot good
He shot a .4ish inch 600 yard 3 shot group last time he came to my range. Groups like that are anomalies, but some people have a knack of getting lucky more often than the rest of us.
I can tell you this, if you are a prarie dog within 1k yards of him you better hope he does not see where his first shot impacts. He is a master at correcting for his second shot....it is freakish how good he is.
