Shooting .50gi is fun! To keep my brass costs down (at $ .39 per case new from Guncrafter) I want every case to serve me as long as possible. And I wish Lee had a case loader for .50gi…different story though. With my .45 reloading I did not care too much about how clean primer pockets were, but now I do. After doing some homework I decided to go for what seems to be the best and give stainless steel tumbling media a try. I got the media, put it in my tumbler with 100 cases of .50gi brass for 4 hours and …waited for the outcome. The results did not impress me honestly. Take a look and you see nice dirty spots in every primer pocket. I contacted stainlesstumblingmedia and got a reply from Cory who sent me more media at no cost to me (way to go for every business who cares about customer sat!), but warned me that the issue is most probably my tumbler, so more media may not help too much. And it did not, as promised :lol: although I have 10 pounds now. So, now to my tumbler. What I used was a “rock tumbler” with a round tank. Very nice, heavy plastic with nothing to wear out, but….a bit too round, I guess Here is the tank I got from Cory which he promised would make a difference. Here it is with nice polygonal shape. The only drawback is that it’s using metal tank with a rubber insert, which perhaps will not last as long as my heavy plastic rock-n-roll tank. We will see…. But indeed it worked. After 4 hours of tumbling (180 cases in the tank and perhaps a bit too much) here is how my brass looks now. Pretty clean, ha? Not sure if better or cheaper solution exists, but this one worked. What is your guys best cleaning hints?
