If you hit a turkey with 130 pellets or 30 pellets in the neck Dead is Dead 100%
The problem with this analogy is that you aren't going to hit a turkey with 30 pellets in the head and neck at 60 yards with number 5 shot. You aren't going to hit him there with 15. You probably won't hit him with 10. And keep in mind that a much, much, smaller percentage of those head and neck hits are going to actually (maybe) hit spine or brain. Only spine and brain hits matter. Pellets that go through his beak, waddles, or skim his neck don't amount to a hill of beans.
At 60 yards with number 5 shot you are spraying and praying hoping for a golden BB as they call it to land in the right spot. Can it happen? Sure, but the odds suck.
