Thanks for the info. my 12ga. has a modified choke and it shoots black magic light magnums good. I have seen alot of you guys cut the choke off and get good groups. I left my 12ga. pardner 28" and just put sights on it, i like the longer sight radius for open sights. If i was to have the 20ga. d&t for scope i would not have a problem cutting it down to 20" or less, would make a great ground blind gun. Thanks again for the info Jeff
