I appreciate all of the positive comments and hope that the information is at least interesting and maybe helpful to you. With all of the available options out there today in the way of chokes, shells and guns, let alone the variations of all those choices, evaluating all of them would be quite a task.
The Hevi-13 project was a pretty natural companion to the WLB project that was recently published in "Turkey Country" magazine. Those 2 projects and the 3rd Degree evaluation that I published, required a good bit of range time and several hours in compiling and analysis of information.
It's time to hunt turkeys this spring and I wish you all well as you pursue those big red-headed birds.
Thanks,
Clark
