Just shot some SST's an hour ago and am VERY Impressed. I have a Hastings barrel on my 870 and factory open sights ( which I have been meaning to change for the last 10 years). The sights cover any small target almost completely, so to a true grouping is impossible. So they grouped reasonably well at 50yds which is no big deal, what impressed me was there down range accuracy. At 150, easily in a paper plate. And they are only supposed to drop 7" at 200. That is what I like!
