come to think of it, i shot a 5 shot group like this the other week with my hw 95k .177 using jsb exact.
the 5th shot was a wobble just about a centimeter to the left, but the first 4 shots went in the same jagged hole, at 29 yards.
i put it on another thread duno who seen it, but i deleted the pics from photobucket so now it wont show up lol.
also after chronoing my 95 the other day the jsb's were also very consistent even unwashed at 13fps spread i think over 20 shots.
so yeah im with bigmac on this one,-- Jsb Exact = very good pellets
