Well Chapa, if it's a rifled barrell, sad truth is a good sabot round will run ya about $2.00- $2.50 a ROUND!. If you want a true 200 yard gun, I'd go w/ Hornandy. I believe they put out at about 2000 fps. Winchester Partition gold is another good one, at about 1900 fps. If your shots will be within 100 yards, I'd go w/ Litefields. They're a bit cheaper also, but pack a hell of a punch. I have yet to shoot a rifled barrell that doesn't like the Litefields. Check the trajectory charton the box, and practice, esp. if you plan on making it a long range shotgun. I've also found that the 2 3/4"shells group better than the 3".
