Mike I wouldn't assume the GOEX can't get the gun regulated. You are going to find a couple of challenges here. First is getting accuracy from one barrel using blackpowder because there is a bit of a learning curve getting the correct powder quantity under a wad and grease cookie combination that works for you. Then you get to see how it regulates and can tinker with powder quantity and bullet weights to bring them together. This isn't going to perform like a modern target rifle. Two-three inch groups at 100yds would be pretty good from each barrel, well regulated a combined group will expand that. If you haven't already found a good reference for black powder reloading, suggest you get a copy of SPG Lubricants Black Powder Cartridge Reloading Primer by Mike Venturino and Steve Garbe. They are shooting single shots but the loading for accuracy is a good starting point.
