I started turkey hunting with a 20ga, and used it for 3 years, in which time i shot at 3 birds and killed ONE of them, only one shot was further than 30yds, it was a miss at about 30-35, the one kill was at about 15yds, and the bird wasnt dead til i beat the thing in the head to finish him, not fun. The other missed bird was the closest of all three, and it was a head-on shot at him so i know i didnt miss, but he ran/flew off
After that, i wouldnt use the 20 any more for turkey, im now toting an 870 supermag, 12 ga, 3 1/2 Hevi Shot loads

I WONT be missing shots this year.
