I have a 500 and 200e 20gauge Ithica /SKB. the 500 is ic-mod and the 200e is mod full. The lenght of the choke tapers seems short to me as they are not much more than an inch long. My question is aside from the chrome bores has anyone had good patterns thru opened chokes that are this short? I have had very good luck with the open chokes of the 500 and hope to replicate it with the 200e. I know Briley tubes are just the thing in this case, but are there other options? Thanks in advance Mark
