Have had fantastic results in both a 26" barrel 11-87 and the short turkey barrel I put on my 11 87 using the Tru glo SSX (strut stopper X) compared to the factory remington turkey choke, factory remington full choke and a really good but old carlsons .665 turkey choke. To me the SSX digests very well several different loads I have run out of it over the years. This includes the old black box winchester #4 and #5 turkey loads and several of the older Nitro mag lead #2 Remington loads which were my back up.
The best results until 2 seasons ago were with winchester XX 1 7/8oz 3" #6 buffered copper. BUT the Hevi shot and hevi 13 in 3" #6 2oz have been fantastic and produced several no wiggle shots out to my comfort zone of 35 yds. I really like letting them get as clost as possible. Gives me time to enjoy the show and calm my nerves a bit. This is what has worked best for me. Really get out there and try some different stuff though before settling.
