Can anyone tell me what the diameter of there expander ball is ? I have a new set of redding dies and they measure .171
diameter on the expander ball, with this being that size I am getting a crease mark on the bullets when I seat them , It seems they are very tight going into the case mouth, like the expander is too small . I'm using new rem brass cut and sized all the same and the case mouth chamfered inside and out, and shooting Berger 25 gr. flat base hp bullets . Any ideas would be appreciated.
