If it is of help, I hunt pheasant in SD every year. Pretty much all you can buy at Cabelas is geared to heavy fast loads like your outfitter is providing. Last year I shot Herter's 1 ounce of 6's at about 1100'/ second in a 16 gauge, mod & full and found it was deadly on them. Don't fall for the hype. If you miss the bird an extra 1/4 ounce won't help.

So many guns, so little time!
