I got a M3 about 1 month ago and tuned it perfectly at 907 FPS MOA @ 100 yard. I had several tin of MK11's from 7 or 8 month ago purchased from Midway USA to tune the gun. Same pellets arrived at Utah Airguns and they were able to fill my back order from several month ago. The new ammo will struggle to shot a 2" group at 100 yards and occasionally a flyer more than 3" out of center. Any one having problems like this with the recent batch from JSB ?
