It's my 1st year loading tss and so far I'm getting awful patterns. Shooting it out of remington 11-87 compact. Have shot it out of carlsons extended .575 choke and factory full,best pattern is 150 in the 10. Same carlson choke puts 170 of federal heavyweight in 10. Anybody have a recommendation of another choke that might pattern better?
You're just too open pal. Some guns are like that for whatever reason and also for whatever reason...I haven't had a gun YET that will shoot a pattern worth a chit with either a flush or extended Carlson's choke. You're gonna have to choke it down some and use a ported, quality turkey choke most likely. Borrow somebody's IC .555 and try it before you try anything else. That cheapo .565 Tru-glo (Gobble Stopper - GSX) that wmd mentioned has also proven to be real consistent in the short Remington barrels too (what we use in my son's gun).
