I was shooting two, but have found a real accurate load with 3 pellets and 240gr XTP Mag going over 2050fps before nailing my chrono. I have to use a MMP subbase with this for it to shoot well. You won't believe how much flatter I shoot with 3 pellets over 2. One I am shooting 2" low at 150, the other I am shooting 6" low. You will never know until you try.
