when reloading my .308's the cartridge is kinking before the bullet becomes tight, any suggestions would be appreciated.
I agree with rimfire_crazed, the die is set too deep and it's crimping before the bullet is seated.
Do they look something like case on the right? I found this when doing some .223 reloads over the summer. Culprit was the crimp collet was contacting the case too soo as a result of the die being screwed into the press too deep.
Sounds like your seating die is screwed down too far. Readjust your seating die per manufacturer's instructions and try again.
You should be setting up your dies with dummy rounds - no powder, no primer.
