Alright; thanks for the advice and the INFO. I had seen the LightFields at the shop but they only had them in stock in 20Ga. I am sighting in at +2.5" at 50 yards, they say this will put me -6.5" at 200yards. Im not sure on grouping yet as i wanted to check out the slug situation before i messed chanced damaging my barrel. What are the actual ranges your would take a shot out to with your slug? I was thinking about 150ish max.
