I want to convert a Browning Micro Hunter to .17 Ackley Hornet. I have never done anything like this. I don't know where to start. I'm going to use the gun as a fox gun. I want to shoot 20 grain bullets to do minimal pelt damage. Can somebody help to get me started? I don't think that I want to turn this over to my usual gunsmith. I would rather have the work done by someone who has experience with the .17 hornet. Thanks for any and all information.
