8"?? i like to get my 22lr down to 1.5-2" at 100yards.... my big bores depending on what cal it is must hold 1.5 or less out to atleast 100yards, most are sighted in at 200yards. My varmit gun 22-250 is 300yards @ 1.5". My bow has to shoot better than 8" for me to trust in in droping game. i like it to hit in 1" circles out to 35yards =)
