I am new to relaoding so i got a lee 50th aniversary kit to start and some RCBS dies. I am reloading .300 wsm i ran into a problem where the case was to long from base to shoulder and chamber without alot of force. I found a redding dealer would shaved my shell holder .007". Now the casings fit but on the shoulder of the casing there are small wrinkles they arent on the body or the neck. Is this going to be a problem or should these be ok to shoot.
