This mold is working very well for me. For some reason the lightest (79gr) and heaviest (91gr) seem to both do better than the middle weight. A totally unscientific comment about BC vs JSB-- at my 80 yard 4" gong, noticeably less holdover is required with the 91gr vs JSB 81gr when both are zeroed at 50 yards. Great pellets, someday I hope to pick up the .25 mold...
