I shoot a 1979 Bear Blacktail Hunter 50# compound bow with Easton 2315 aluminum arrows. My first pin is 10 yds, 2nd is 15 yds & 3rd is 20 yds. I just mounted a TruGlo site on it & I'm shooting 4" groups at 20 yards. I'm no Howard Hill, but I should put plenty of meat in the freezer again this year.
