Bought a couple of extended chokes for my Browning Citori 625 from Comp-N-Choke in Atlanta . Tried them on sporting clays tonight and I think this spreader choke with negative restriction(bigger than cylinder bore) is great for those really close fast birds. Actually I shot some out to at least 30 yards with it. The chokes seem to be very well made and the folks at Comp-N-Choke were great to deal with. I wondered why my purchase didn't show up on my credit card so I called them and they had written the number down wrong,but had sent the chokes anyway! This was my first time dealing with them. If you're in the market give them a call,they have a good website.
