Things I liked:Whats not to like? These Supermag are accurate in all rifles I own. First pellet to fit this bill. Air Hawk/Stoeger X20/Bam26 are shooting the best groups with these pellets, quarter inch and smaller. Great knock down power too with the 9.3 Grains weight. Things I would have changed:Nothing comes to mind, very pleased with this product. What others should know:After trying many different pellets with my tuned AG's these are the only pellets I can really shoot one hole groups at 20yds to 35yds.
Things I liked:Chrony was simple to use, just unfold it and start shooting. Operation was straight forward, had data in a few minutes. Things I would have changed:Nothing! What others should know:Only problem would be adjusting lights for indoor use. I hung a over head light above the unit, @100 watt bulb worked fine.
