I have had this same issue with SR 7625. Too many squib, random pressured amounts resulting in some shots being too soft or failure to eject the fired brass. I have not had this issue with Titegroup 4.5 grains at 1.125 COL. Obviously most on here would say that its user error -- my inability to reload accurately. But I have been trying to tinker with the Dillon 550 in order to get an accurate load. For the time being I'll just stick with titegroup. I hate going to the range and having to worry about ammunition. I feel time at the range should be use to improve my shooting skills.
