Ok for me at 40 yards I have to have at least 50 BB's in the head and neck area for it to be acceptable. A lot of the others on here wont agree. I have an awesome shooting gun. I shoot a Mossberg 500 with a factory turkey choke. I have an xx-ful turkey choke. Now remember you have to hit the vital areas. I mean it only takes one BB to do the job. I patterened this gun until I found the right combination. I have to say no turkey has ever left when Ive put the bead on them. The more BB's in the head and neck means more BB's in the vital areas. I wouldnt sell the gun I own now for anything. Its just awesome. Pattern you gun and find the right combination. Myself I love Federals. Try some Federals.
