loaded my tumbler 5:30 am this morning with 5000 pieces of 9mm brass.(yes ...it is a concrete mixer, modified.)
3 gallons of hot water , a pinch of citric acid and 3 ounces of armor all car wash & wax.
25 pounds of ss pins.....
put my cover over the hole and locked it in place.
turned it on.
forgot about it in the garage churning away for ....oh.....about 11 hours.
now they are in the brass drier (well 1/2 of them are anyway.)
yesir!
thems is the cleanest i ever did see!
primer pockets like new....insides are just as clean as the outsides.
