what aftermarket chokes do you use while duck or goose hunting. I use a briley duck choke now but might be looking for something a little tighter. The duck choke is considered a light mod but yet it holds a tighter pattern then my remington mod choke does at further distances. I did a little reading on patternmasters and the other big name stuff and came upon a smaller company call drake killer. They custom build the chokes for the specific bore size of your gun. it seems like they have done alot of experimenting with their chokes, different guns, and bore sizes. once you get a choke they tell you what shells to use with it to give you the best preformance. I have not found too many people upset with them at all so i was leaning towards one of their chokes.
