Nope, they bounce off turkeys.

Actually, I used 1 1/2 ounce #6 Remington hevi shot waterfowl loads last year, and they did a great job. They patterned better than anything I have tried in my 870. I try not to shoot long shots, but I horribly misjudged the range on a 21 pounder. Killed him stone dead at a ranged 47 yards. He didn't even flap. After all these years, it takes a lot, but I have to admit--I was impressed. And, of course, they were just as deadly on my normal (35 yards of less) shots.
