bloodtrail,
Great deal on the gun! Yes, it is a VERY decent gun. I have the original Wolverine and have had it for years.
Knight does make a conversion kit for this gun. I would recommend that you get the 209 kit that uses the Full Plastic Jackets. Much better than just the standard 209 kit. The newer Wolverine II's have this kit pre-installed. That is why you got such a great deal. The kit will run about $60, check out Bass Pro Shops for it. You can definately use the pellets in this gun, and I believe that it can take a load of up to 150 grains. Please check with Knight first, to verify this, as the older models of the Wolverine only went to 100 grains, max.
