Go back to the Remington 1100 12 gauge or wing master 12 gauge is my advice. And as puppy gets older he will find more of these birds for you, although no matter what, a few of the wiley hit roosters find a way to dissappear.
I almost downsized my turkey gun. Glad I didn't. I had a nice Tom come into my view but wouldn't commit, he had a hen right with him. Finally the hen walked back the way she came, but 5 yards closer to me. It was all I needed. If I would of had a 28 gauge that giant Tom would have walked away Scot free. As it is he's in the deep freeze, on his way to being turkey jerky. I have a picture to prove it, but not on my phone.
