holy moly, what a fix for 15 dollars. my last range visit yielded just over 2 inch groups at 100 yards. with the pin installed i ust shot an honest 1.25 inch group at 100. thats 100 grains white hot pellets, 250 sst with lowdrag sabot and a 777 primer out of a Encore pro hunter with a 3.5- 10x 40mm scope Leupold with leupold mounts. i am anxious to shoot 150 or more at the range, but for now it is off to the Adirondacks for early bear season. i will check in on monday or sunday night
