Having problems with this one. Started with 30-06, swaged base to .446". Formed case with 6,5 x 52mm sizing die with shell holder extended full length, just touching die. The shoulder is not being pushed back enough. Length to shoulder is 1.685", but should be 1.618". Guess I could push the case up into the die without a shell holder and knock it out with a punch, but is this common? Thanks, Dan
