Dense pattern - Carlson's Choke Tubes CORE 12 Gauge

it does throw a awesome dense pattern at 20yards with the 8shot I tested. Carlson told me the core series is so new its not even on their own website yet, but its for sale in these online stores. figured it's a good all around choke for me. I don't need the 100 chokes they offer for 100 things. this close range plus a long range is only 2 i'd need. thanks
