RE: hevi shot....
There's no guarentee your gun will shoot the hevis best. I went out today and ran a box of hevi's through my gun and 2 different chokes, but was extremely unimpressed with the patterns I got. That being said, I've seen and heard alot of people who got great patterns with the hevis. If money is tight and the Federals are shooting good patterns, I think I'd stick with the Feds. If you get some extra cash, you may want to try the hevis, but like I said there is no gaurentee the hevis will shoot well outta your gun.
