Try admusting the seating die up a little where it isn't touching the shell holder, if your bullet is too long for your seater die?

that has worked for me when I was loading some for a friend or two...

until recently, I didn't own a Creedmoor.. but I've had dies for the round for a couple of years..picked them up on sale for like $10 to $12 off regular price...a set by Lee for like $20....
