Went out scouting this morning looking for a bird for my fience to shoot tomorrow and had one work really good. A couple years back she went hunting with me and took my 20 guage. It has been a couple years since we patterned it for turkeys and I can't remember how far out it held a good patern. I won't have a chance to shoot it today so does anyone have any ideas what the max range it will have? Rem 870 3" with a modified choke. I might have a chance to get to the store today & pick up a full choke, that is if they have any. I am guessing with a modified choke 20 guage the max distance will probably be only 30 yds?
