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. 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 Dawn dishwashing soap and a pinch of Lemishine 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. If you choose not to have the polished brass, I eliminate the Lemishine, and only tumble for 20 mins. 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. On occasion, water spots may appear on the brass due to the drying process.
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.
Cost of brass shipped and insured is $2.35 each:
50 - $118 100 - $235 150 - $353 200 - $470 250 - $588 300 - $705
This is an oldie, but my process has not changed that much over the years
