[QUOTE="Kennibear, post: 903554, member: 51650"] DocB Proceedure is: 1) Decap as a complete step. 2) Clean the primer pocket with a RCBS brush and clean the neck with a stainless steel bore brush at least one caliber larger (i.e. 40 cal pistol brush in 375 cal rifle etc.). I chuck the bore brush into a drill to speed it up. 3) If the cases are cruddy I wash them in dishwasher detergent and dry in an oven set at 170 degrees F. 4) Size at this point. Lee collet neck sizer for bolt guns but FL for the automatics and revolvers. All straight sided rifle (45/70) and pistol cartridges get a Lyman "M" neck expander. I have considered pulling the expander balls out of the FL dies and use a dedicated "M" neck die for each caliber. 5) For ammo going into long term storage and really dirty brass I use a dish soap- dishwasher detergent- citric acid- dishwasher detergent neutralizing wash- triple clear water rinse clean cycle w/ 170 Degree oven dry. 6) Prime the cases with a hand priming tool- even for the progressive loader. 7) Powder charging. 8) Bullet seating. Hope this clears this up. I FL size a case and as I withdraw it I feel for the case to clear the neck. Then, holding the case up into the neck, I adjust the expander ball up into contact with the inside bottom of the case neck, then screw the expander rod down two full turns but leave it loose. Now pull the case down into solid contact with the expander ball and tighten the expander rod lock nut. This locks the expander ball inline with the case neck as it is withdrawn from the die. This is the best way I know to set up a standard expander ball set up but requires separate decapping. But I like that part as it allows me to thoroughly clean the case before I drive crud into the sizer. Anything to minimize runout and wear/work hardening of the case. KB [/QUOTE]
