tanfogliocoe Posted February 28, 2013 Share Posted February 28, 2013 I just switched to extreme bullets from black bullets. When I crimp the round, it still spins in the case. There is plenty of crimp. Is this something to be concerned about?? Link to comment Share on other sites More sharing options...
Jaxshooter Posted March 1, 2013 Share Posted March 1, 2013 Crimp should not be what is holding the bullet in the case. Neck tension is what holds the bullet. If it spins sounds to me like you could also experience bullet set back which can be extremely dangerous. Link to comment Share on other sites More sharing options...

I only crimp enoung to take the "bell" off, maybe slightly more. Over crimping with lead, or plated bullets usually cause accuracy problems. Are you using a Lee, final crimp die? If so, that could be your problem. The lead downsizes, but, the brass, especially if hardened, springs back. Link to comment Share on other sites More sharing options...
