I hunt with my winchester 1100, 20ga. a few years ago I was using 3in, regular turkey loads with no choke. now I tried something different last year I bought a box of those new heavy load shells by Remmington. I shot a 19 1/2lb tom last year with those shells and dropped him dead at 40yrds. 40-45yrds is the farthest I will ever take a shot at a bird.
