I got a Franchi 2 seasons ago, and I am ok with it. But getting my new CZ made me realize I am a lot better shot than I thought! I looked in the box and it came with a shim set, I have gone down the rabbit hole and back on trying to understand what the numbers mean and how to maybe pattern it myself. But at this point, I would love some direction or some help! If you have a good Youtube Tutorial, or suggest a good range to do it, or person. I am all ears. This is all pretty new to me still, I have the tools, but again not really sure what I should be paying attention to.
