I'm saving up for the h&r 12 gauge ultra slug with the thumbhole stock. I plan on putting the truglo 4x32 tactical mil-dot scope on it. It's a FFP fixed 4x. My 5 questions are : 1. How do you sight in a mil dot / turret scope? 2. How long is a mil at 4x considering most mil dot scopes are 10x+? 3. Can the truglo scope handle slug recoil? 4. Im not going to shoot farther than 200 yards ; how far should I sight in at to get the most use out of the reticule (I have a laser rangefinder)? 5. Which scope would be better for slugs : the truglo mil dot scope or the tasco 3-9x mil-dot scope?
