Frankford Arsenal Walnut Media Treated and Untreated, 5LB- 18LB, for Ammo Reloading, Shooting Bag Filling, and Case Tumbling

I use straight regular brasso, with the medium grit walnut shells in the tumbler.Brasso : https://www.amazon.com/dp/B00UUI6Y16?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_4 Tumbler : https://www.amazon.com/dp/B001MYGLJC?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3 I got the walnut shells at Harbor Freight, but I think these are equivalent : https://www.amazon.com/Frankford-Arsenal-Tumbler-Reloading-Shooting/dp/B0063GTFXS/ref=sr_1_6?sr=8-6 Usually leave it running with them in it in the garage for 24-48 hours. I do this for all the small things I pour that fit in it. Sometimes up to 72 hours. load the shells up into the tumbler, then squeeze in around 1/4 bottle of the brasso, then let it run 5-10 minutes to work in the polish, then dump in the pieces.
