I don't doubt the damage. A lot of people are putting well over 300 pellets inside a 10 inch circle at 40 yards with H-13 number 7's and a good choke like a Indian Creek BDS, Jellyhead, Pure Gold or Rhino. At 35 yards those numbers may well jump to 375 or so. Thats a lot of bad Ju Ju if you get a pattern that dense centered on a gobblers head.
