I played with the brass and kind of impressed. Most was within 6 tenths of a grain in weight. Trim was within .003 and no big dents or dings. Mouths was normal for brass in a bag/box and good rolled over edge on outside of mouth,, from the normal factory trimming process. Primer pockets looks good and decent flash holes.
So this is what I did. Removed the decapping unit from the die and put it in the drill. Ran it for over 30 seconds with 0000 steel wool around the expander ball. Degreased all and ran again with toothpaste between my fingers. Then ran on leather belt. Lubed the inside of case mouths and just ran over the expander ball and right back out. Trimmed all to .002 below min. Chamfer / Deburr and uniformed the primer pockets. Very little shavings was on the prep center, after doing 50 primer pockets. I like to have it clean when doing the pocket depth, to see how much was removed. VERY LITTLE and could pick up all with a press of your finger tip.
Lets check run out. O heck and have .003 to .010 … That not good and ran two cases that was .008 to .010 off,, into the die,, 3/4 of the way with decapping unit removed. Now we have .003,,, so I did all the same. Most if not all is .001 to .004 and said screw it,, after 25 or so being measured. Then I ran them back into the expander ball only and still have .001 to .005.. Done and they have to be fire formed anyway. I just figured it would be best to prep the new brass, best I could and kill three or four birds with one stone. Brass break in, Barrel break in, half decent data and accuracy promise. Why not and no use to just shoot 50 times,,, for nothing other than forming brass and barrel break in. Start out with high expectations / do your best and seems to pay off. I usually buy two boxes of factory rounds when getting a new rifle, but not this time. Reason for getting factory is if the brass cost the same or more than factory rounds. Next is just to break the barrel in and have brass. This rifle is differ and brass is .99 each and box of good ammo is 35 bucks. Have 100 pieces now, so that really means 85 or so, after culling out the few that causes major fliers and finding the limit of charge.
