I don't mean to Hijack the thread but......I recently quit using Claybusters version of Windjammer wads for what I believe is a similar reason. one in five would "snap" as it was entering the hulls (sts), I didn't think much about it since I would guess we have all had the same thing happen on occaison, at least on a MEC loader, well I loaded up a flat or two and shot some last week. The first box was full (15-20%) of weak sounding loads, hollow pops that shot but missed, I can only guess that the issue was some sort of tipped wad??? I really don't know, but I switched over to Fig 8's and have not had ANY issues. I quit using Claybuster AA wads years ago because of this snapping, but I never had any off sounding or weak loads then, like now with the Windjammer/Cbusters. I notice that the W jammers are very soft/flimsy plastic as compared to the Fig 8's, not sure if they are so soft that they can easily tip the cup?? Has anybody else had similar issues??
One thing I will test is upping the load a bit, the loads in question were 1 1/8 with Win 209, 16.5 g 700X, and is at best an 1150fps load. Is it maybe too light for the CB Windjammers??
