C120, I feel your pain. I am new to the smoke pole world and having the same troubles has you. I having larger than expectedgroups at 25 yards. You might want to ensure your scope is tighten down. Last night I checked mine, per someone's recommendation, and sure enough some of the screws were a little lose. Not sure if this will help since I don't have a range to go to, but could be your problem as well. Hope you get you smoke pole dialed in. Good Luck my friend!
