i got a STM rebel 17 tumbler for Christmas and used it today to tumble 50 pieces of 260 brass...pre instructions i added 1gal cold water,3Tbs blue dawn,1/4Tsp LemiShine and tumbled for 3hrs. checked cases and insides were still kinda dirty(which i dont really care)so i ran them another hour and insides still dirty and i guess a 1/4Tsp is to much LemiShine because the case are tarnished now which i dont mind either as ive never cared what my brass looks like only that it shoots. i cleaned the drum and media and added warm water and 2Tbs dawn and put them back on for 45mins...will be done in 30mins ill post some pics when done.

so for you guys that are tumbling with stainless pins what are you using? any tips for a newbie?
