RE: best waterfowling shells
Kent patterns in my gun better than the xpert, but the main reason I decided not to go with the xpert (although there is a big difference in the price) was the powder residue the xpert left on my barrel compared to the kent. Major difference. I'm a bit anal when it comes to cleaning my guns and the Kent makes a huge difference for me. That said, my buddy uses the xpert; hasn't cleaned his gun in two years, and it just jammed up for the first time last week off 2 3/4 inch target loads.
To each his own I suppose.
Are you planning on using the same shells for both ducks and geese? I know guys who have had great success just buying a bunch of 2's and using them universally. I'm going to use 3's for ducks and 1's for geese (both 1 1/4 oz loads @ 1425 fps).
Good luck
