I am having problems with the case increasing it's diameter right below the shoulder when the bullet is seated in the seating die. The bullet weight is 150.5 grains and 0.308" in diameter as the box label say's. I have used virgin brass in Win and Remington brands and fired Remington brass with the same results. This was done making up dummy rounds since I am also having problems with COL. Ramshot's books say's that COL is 2.725'' and Hornaday's say's 2.735". Neither of those two lengths will fit in the Rem 700 nor the L1A1, but a COL of 2.68" will and that is way past the cantulers (sp?)
Any suggestions?
