I switched to them last fall and I am getting almost 1 hole groups at 50yds, all holes touching.I have never shot a group at 100yds because I don't have the place to do it.I was useing 2 pellets of triple 7.I shot this doe at 60yds and she ran 40yds at the most.Left an awsome blood trail.I bought 6 packs of them for $9 at walmart when they went on clearence,still have them.
