RE: yardage?
I have used the .243 for a lot of years wood chuck hunting. My favorite bullet is the Sierra 85gr BTHP sighted in at 2 1/2" high @ 100 yards. I have shot chucks 300+ yards holdng right on the neck! Remember,you have to have good optics if you want to shoot long range. Good Luck...<img src=icon_smile_big.gif border=0 align=middle>
