Stop before you hurt yourself. You need to get rid of those ASAP. Send them to me and I will see that they are safely disposed of. Seriously, Lee data is correct about the crimp. It has to be very light otherwise you could damage the bullet. I think 5gr is a little weak for a lightly crimped 125 gr bullet. The frangibles I loaded were only 95 gr but the bullet length was the same as a 180 gr FMJ. I used a light crimp and after several try's settled with 6.5 gr in my loads using Win231/HB-38. They all worked great. Just wish I could find some more at a good price. MV across the chrono averaged 1500 FPS from a Glock 22. I would work up some more reloads using a heavier charge, say 5.5/5.7 and pay close attention to the crimp and OAL and see how those do. Good luck and play safe.
