Sounds like y'all have a culture based on having your heads up your own backsides. Where we have common sense, we use shot to limit lethality.
Considering turkey hunting regularly tops the HRSI totals for hunters shooting other hunters and has since well before TSS existed the whole “we use common sense” doesn’t exactly hold water when your argument is that you use less lethal shot to reduce the chance of killing someone because you failed to properly ensure it was clear down range before firing.
The much better alternative is to just not shoot when you don’t know what’s behind the target like the vast majority of hunters do while rifle hunting. Most turkeys are killed on the ground so it should be easy to set up with a proper backstop.
