Man, I tried sighting my shotgun in with slugs and gave up on the idea when I was hitting about a 16 inch group at 75 yards. At 50 yards it was an 8 inch group. Too risky to take a shot on a deer and take the chance of wounding it with that setup. I would love to see some of these 150-200 yard shots with a shotgun though, I know it can be done, but in my experience I have yet to see it.
