Case capacities for stainless steel tumbling?

[Syntax Error]

I was wondering how much brass you can put in one of those Thumblers Model Bs with the 15lb drums? Stainless steel tumbling looks appealing but the specs only call for like 2lbs of brass, which doesn't seem like a lot. How much brass such as 223 or 308 are you guys putting in your stainless steel tumblers at a time? The thing that's making me hesitant is efficiency because the times I can tumble without disturbing neighbors in my apartment complex are relatively limited, so doing as much brass as possible in a limited amount of time is key.

I stick with the recommended 2lb's of brass +-225 pcs. As far as efficiency, you might be tumbling less brass at a time but in two hours your brass will look better than dry tumbled at 6 or 8 hours. I am currently tumbling some really nasty range brass, I took a peek after an hour and it was bright and shiny on the outside. I gave it 2 hours and it is as good as new. Completely clean inside, outside and primer pockets. I thoroughly rinse with clean water and put on a perforated pizza pan in the oven for 15 min @ 200 degrees. I won't tumble brass any other way!

When I had one, I would put at most 2.5#. Overloading it will break the belt and could burn out the motor.

Have you looked at the Frankford Arsenal Tumbler?

I insert the pins first.
Then the brass, filling up to the 1/2 way depth.
Then enough water to cover the brass.

All that extra water is not helping the process and the weight is not required.

I figure between 10,000 - 20,000 depending on cartridge and how randy I'm feeling
