I've been fortunate enough to harvest a few turkeys over the years with my 870 super mag with a 23" barrel and Indian creek .665 I've been using hevi-13 in a 3.5" 2-1/4oz load of 6's. Well I'm down to a box of 5 and I believe there discontinued. I've noticed most of the shells went up to around 80.00 for a box of 5 and I'm just not paying it. Before hevi shot came out, I used a kicks in .665 and the Winchester double x's at 1300 FPS in 3.5" 2oz load of 5's. I got plenty of these shells left along with the Winchester long beards in 5's and 6's. I was thinking of trying a jebs and a sumtoy with one of these shells. Anybody got a recommendation on the constriction.
