Boltman, you would lose a 100 dollars.

You should always decap your brass in a separate operation. Then thoroghly clean your brass inside and outside. The dies should be checked and cleaned as well. I use Imperial sizing die wax, its the consistenciey of shoe wax, you can apply it with your fingers to each case and touch the case mouth to the wax, this will lube the expanderball as it goes in then out of the case. Clean the wax from the newly sized case and check to see if it chambers. A lot of case strtching occurs when the expanderball gets pulled out of the case. The bullet seating die is best adjusted by useing a factory loaded shell as a dummy case. Back off the bullet seating stem then lightly screw the die down till it makes contact with the dummy case. Lightly screw down the bullet seater till it touches the bullet. Mark this setting on both the die and the press with a pencil. Now see if you can make a round, and see if it chambers. You may need to adjust the die again slightly to get a crimp on the bullet. If you marked the die you will have a reference point to work from, just turn the die a few degrees at a time till the crimp is right, a quarter turn of the die might buckle the shoulder of the case at this point while a sixteenth of a turn may not. When the die is adjusted correctly mark the die and write down the correct adjustment in your load book and inside the die box so you can set up the dies in an instant next time. I check each round for overall length and to make sure that they will chamber in the gun, a hunting trip is the wrong time and place to find out that your ammo isn' t going to work in your gun. Good luck hunting!

Has anyone mentioned OAL? Someone mentioned ogive, but if the OAL for the bullet is too long it will definetly be hard to close (especially if it is crimped).
My son and I both have .30-06' s and we prefer fire formed cases, but his is a little bigger than mine and his requires a less headspace, so we mark the cases and keep them seperate. I know right away if I get one of his cartridges. Mine will fall into his gun though.
