I read the topic to this and my first reactions was "take it easy on him he is new" DEAR GOD BOY, and you added the .17 comment to the mix to boot! HAHAHA! Welcome to PM bud, sounds like you got a few gizmos on there.
I have had the same problem, it wasn't the bullet, it was me being a terrible shot. When I hunt at night I almost always use a shotgun. Dont worry about an IR lazer, I have never used one before but from the sounds of it you are having trouble mounting it to your shotgun? Duct Tape?
good luck, your posts need more pictures, especially of your gear. get with it bud!
