You will find nowadays that ANY load listed as being for turkey is using plated shot. The copper plating decreases pellet deformation which has a twofold advantagous effect. 1) Less pellet deformation means tighter patterns. 2) Again, less pellet deformation usualy means deeper penetration. I would pick up a few boxes of different Turkey loads. Shot charge weight isnt too important as long as you are dumping about 6 or more pellets in the head/neck area for a clean kill. Pattern your gun a 10 yard intervals as far out as you plan on shooting. I think 30 yards is plenty, but thats me and you will have to decide. As long as your getting proper pellet counts in the kill area. Some bbls/choke tubes arent rated for hevi-shot because it is made from Tungsten Iron, whic is as hard as your bbl. This will cause scoring and marking in a bbl and choke tube not meant for it. Plus, because it does not deform at all (unlike the lead does) too tight a choke will mean a burst bbl for sure. Besides, I was using hevi-shot the past couple of seasons, but the price of the dang things, plus the fact I only shoot out to about 30 yards, meant I was wasting money for nothing.
So just pick up yourself some boxes from the likes of Federal, Winchester and Remington and pattern. Pick the best load for you and have at it. If you do pick the 2oz loads just remember one important thing.......TUCK THE GUN IN YOUR SHOULDER! Lets just say failure to do so will result in bodily bruising :wink: .
