experimented a few weeks ago on a US popper. using WW aa's 2 3/4 dram, 1 1/8 oz #7 1/2 in a 26" model 1100. popper fell consistently out to about 26 yds with an IC choke-after that, iffy. keep in mind i was taking a long sight picture on the popper. swithed to a full choke and that us popper was going down consistently out to 44 yards, which was hard for me to believe.
