I bought a Shockwave and decided to put a stock on it so I ordered a Magpul. Seeing as I'm going to put a stock on it and it already has a rail, I might as well mount a red dot that I have sitting here. I was wondering how most people sight in a shotgun. I was thinking of buying some slugs and setting up a cardboard target at 25 yards or so and shooting off a front bag rest on the bench to sight it in. Is this somewhat correct, or is there a better way?
