I was waiting to see what was said about them, anyway they are caused be an uneven pinch trim. if its not square you will get folds.
^^^^^^^ I'm with George on this - I had a LOT of, the seemingly defunct Hines, 224/.705" long jackets, purchased through Bart Sauter, which folded at about 30-40%! I had no sooner begun using that LOT, and was going to call Bart to learn what could be done, when, proactively, Bart called and advised
that I should stop using them, and return them. This was done, and the jackets returned to Hines, and replaced.
To avoid being completely left without .224 jackets, I retained one case of those jackets (10K+), and thinking that work-hardening promoted the folding, put them in the oven, punched-in the "draw back" program and looked forward to, "the cure" . . . the draw back reduced the failure rate to, a still unacceptable, about 25%.
So, I called and cried on George's shoulder - his advice was to put my pinch-trim die to good use . . . "
AND THAT was the cure". Following pinch-trimming, making the entire 10K into a little shorter bullet, resulted in but a single fold. Powerful evidence that George was correct - and as, usual, pointed me toward a solution which cost me a little time, but saved me some $$.
The 47 Gr. bullets shot GREAT & "sold like hotcakes" . . .
Again, Bart/Hines replaced all of the returned jackets: excellent service AND excellent bullets. RG
P.S. Fold rates are generally 1-2 in several thousand pieces: occasionally, I've had a few irritating LOTs which folded at 2-3% - fortunately, "a few" is key those LOTs were FAR apart and far from the norm.
