I've used a 20g with 1 oz of #5 on wild SD pheasant and never wanted for more gun.

I have a friend the doesn't like straight stocked guns and only likes 12ga. I loaned him my Ithaca 3E 20g with a straight stock to hunt some pen raised pheasant, chukar and quail and he loved my guns and now thinks 20ga is perfect, but says he doesn't like straight stocked guns still. Then I reminded him my gun is straight stocked. He didn't believe me. I had to show him a picture of it.
