Exactly right. Depends on which your gun shoots the best. Every gun shoots loads differently, and has one that it just really likes. Have fun, shoot different loads and shot sizes, and one will work great. I agree with the 4-6 range, but if it's legal in your state, don't overlook 2's. They wollop the heck out of them. Unfortunately, here in MO anything larger than #4 is not legal, so check you regulations.
