I like 3 inch #2's until they start to get substantial fat on them, then I switch to 3 inch BB's. Hunting with deke's is great, let their feet just about touch the ground or water, then have at it. I always aim for the head, if they are close you get a CNS kill, or if a little further out, a good body shot, or broken wing. If your lucky, you might even get another round or 2 in the gun before the rest bugger off. I also make sure I use anything over 1550 fps, with steel, speed kills! Kent makes a good shell at a reasonable price.
