I only use Lapua brass when making my 30br brass. Lapua brass is very high quality, and if properly sized after firing, will most likely outlast the barrel you are shooting it in. I first take Lapua 6br brass and check it for defects. I visually inspect each and every piece of brass for flaws in the shoulder area. This is very important as a portion of the shoulder area actually becomes the neck during the sizing up process. I usually cull out 2% - 3% of each box during this process. Some flaws are very noticeable, but some are not. After this visual inspection, I neck the case from .243 to .308 in a RCBS Rock Chucker single stage press with a K&M expander mandrel and Imperial sizing wax as a lubricant.
Next I turn the brass to your specifications using a PMA shell holder chucked in a Dewalt 20volt cordless drill set on low speed. I use exclusively PMA model A neck turners with a K&M carbide cutting mandrel installed (this removes any inside donut that may have been formed during the necking up process). On all the necks, I make 2 passes with the PMA turner to get the necks to precisely the correct thickness. I cut slightly into the shoulders to help eliminate the donut reforming in the case necks.
At this point I take the brass and place it in my Thumblers Tumbler with SS media for approximately 45 minutes. This not only is to clean the lubricants out of the brass, but it also polishes the brass to a high gloss. I remove the brass from the tumbler and rinse it in cold tap water to remove the cleaning agents. Then I place the brass in a Frankford Arsenal brass dryer for 1-2 hours to ensure all liquid is removed from the inside of the brass. If you do not want the high gloss, please choose "not polished" when ordering, and I will skip the SS media step all together. This may leave some reminisce of the wax or turning oil on the brass, so this needs to be removed before the loading process is started.
When you receive your brass, it is ready to size, prime and load. I do not trim to length or alter the primer pockets in any way as I believe this should be done after firing.
