My longest "successful" shot was 40 yards + a bit of a range mis-estimation.
Going into my 46th spring season, my lifetime average shot (compiled across every bird I've ever shot, spring & fall) is 28 1/2 yards.
I know I'll step on toes here. And quite honestly...... I don't care and am not interested in the arguments or justifications. But any shot outside of 40 yards + an honest margin of mis-estimation isn't a "successful" shot whether the bird dies cleanly or humps off to die under a brushpile.
Turkeys ain't groundhogs. They aren't "targets of opportunity". Vermin to be popped whenever possible. They are regal game animals that deserve and demand an ethical, fair chase opportunity. They deserve to be fairly & squarely defeated before they are taken. All the excitement in a spring turkey hunt happens inside 40 yards. A guy who can't call one to 40 yards or less has not been "successful". If he's routinely and knowingly taking shots at 50+ yards, he's a turkey "shooter". Needs to buy a varmint rifle and shoot prairie dogs or groundhogs.
Having been at this as long as I have........ I am not ashamed to say that I still can be pretty badly fooled by distance in some open woods. But, I began carrying my compact bowhunting rangefinder a couple decades ago. It all but eliminates the turkey shooter's crutch of mis-estimation. "I thought it was 40 or 42 when I shot, but it ended up being 66 yards...... " Bullchit.
