Well i just purchased my new a400 needless to say its hard to find chokes out there for gun. Did some research and didnt really find anything other than the kicks. Now discovering this website alot of ppl have had good with the pure gold and jebs. Needless turkey season is almost over here in ms and wanted to use it before it is over so i just ordered the kicks gobbling thunder .680 thinking im going to use #5, 3 1/2. this was before i found out about the other chokes. From other ppl on here have heard some bad news about this choke saying it doesnt pattern well. Reading up that pure gold ppl have used the .670 and had great results, Do you think that kicks would exchange for the .670? and would it be the same as the PG .670? Thinking that they wouldnt do a refund thought this might be better than ordering another choke.
