Think back to before tss of how many turkeys you had at 55 to 60 yards that never came any closer and you didn't shoot. A friend that uses TSS told me he killed a gobbler stone dead with 1 shot from a 20 gauge at 70 paces, and he's a long legged dude.
That 25 yards between 35 and 60 might as well be a mile with lead, but with TSS it's a dead bird and a reduction in population.
The shrinking turkey population is too widespread and too varied to be natural causes, it's happened because we've invented ways to kill them farther and easier and we've done it.
The answer IMO is ban TSS, use of decoys except for bowhunting and have a 30 day/2 gobbler limit beginning the first Saturday in April with tags for checking in the birds and no out of state hunters for the first 15 days.
Plus how many posts do you see every season about "missing" a bird at 50+ yards? How can you miss a turkey with a shotgun at 50+ yards unless you were aiming at the sky? They didn't miss. That bird got plenty peppered, and possibly will die of infection, it just wasn't killed instantly.
These long range TSS shots are making it too easy. And I'm right there with you on the frustration of a gobbler hanging up at 50-75 yds. That's the challenge though. Either work him within 35 yds or he wins that day. IT'S OK IF THE TURKEY WINS!! We don't need to shoot him at 75 yds, or worse, sit behind a male decoy so he comes rushing in.
The male decoys, especially, need to go. Male decoys basically short circuit a dominant gobbler's survival instinct and he goes running in for a fight. That bird is otherwise known as the "unkillable" gobbler that doesn't come to hens. Hens come to him and he knows it.
Only after he's knocked up his entire harem of hens will be be vulnerable to a call. And that's the gobbler that we want breeding all his hens, not dying opening weekend because some flat bill dork needs a guaranteed kill for his YouTube content.
