I was wondering how common this was also. I only have 1 gun and its a Mossberg 500 12ga. With slugs I can hold a 5-6" pattern at 50yds standing up (no rest) with only the bead sight. This should do the trick if I can stalk up to one. I'm looking at getting a Rifled slug barrel for sabot slugs and mounting a scope to it as well. I like the idea of 1 gun to do it all hahaha. Plus I'm on a tight budget.
