    You shotmakers: What size drills do I need to drill shot holes for my Shotmaker? I'm using #8 and 7.5's I'd like to drill some double drippers. Any advice from those of you that have made them. I have a mill and lathe.

    The size of the drill bits depends on the shotmaker you're running and the voltage.

    My Littleton 110volt uses #76 for size 8, but I've seen others with different size drippers making the same size shot. If you have more heat and move the lead through faster, the size varies. I have three 220V units and one 110V and have never use anything bigger than #72. Some people are not real concerned about the size of their shot, because of the shooting they do it really doesn't matter.
    My shot is used by people that compete in registered trap and the size is important.

    I've made drippers and they are not easy to do. I buy them whenever I can.

    Good luck,
    Ajax

    It also depends on your Lead ... if you use wheel weight the size will run smaller than soft lead ... use high quality drills and lube on the drills ... you ask the question about drill size ... smaller the hole ... smaller the drip ... so you end up with smaller shot ... I have drilled out single dripper's to make them double's ... the drill life is not good even with high quality drills

    Drills and bolts are a lot cheaper.
