Cleaned Brass Shells Today:
 

I recently obtained some 10 gauge 2-7/8” vintage Winchester brass shells as well as some modern Parker reproduction shells. I wet tumbled them for five hours in stainless steel pins, dish soap and a pinch of Lemi-shine dishwasher additive. I am always impressed with the results.
I have a nice stash of brass 10’s, 12’s and 16’s but I always try and add to them when I can. Those original Parker Bros. 10 gauge are still out there somewhere, I have a few 12’s though.
