what size choke tube do you use in a 870 super mag. years ago i just used a full choke was wondering what people were useing that worked best now days. thanks i see people useing extra full chokes now. getting the itch to chase turkeys again still have all my stuff. a little late in the season but will give it a try any how. thanks

I use a extra full rem choke but shoot 2 3/4 6's which is good enough for 45 yds easy but you shouldnt need to shoot past 20yds
