You can use your polished brass as signal mirrors if you get lost.
So far with over 6,000 223 and 8,000 9mm no pins left in the brass.
I must admit to cranking that bingo-like ball quite a bit-about double what is suggested.
I run between 75-85% of suggested capacity.
TiminTn noted the peening effect on case mouths and I get that issue on all brass but Federal. Solution is a quick twist of the chamfer tool. Don't see it on 9's.
I do not SS nickle plated. However I do wet tumble them for a short period of time with this purple stuff. Really cleans them nicely. Highly recommended on all pistol cases
The Dawn I use is the Platinum variety. Hate to say it but this Dawn actually lives up to the label. Cleans the brass or SS
very well and works in the kitchen also. Very good for everything but the dishwasher.
