[QUOTE="Pdvdh, post: 1128882, member: 4191"] My method is similar, however I've been pre-heating my bullets just prior to vibratory tumbling in HBN powder. I clean bullets with acetone. Air dry a short period of time and then preheat bullets to ~ 160F - 170F in oven, just prior to placing hot bullets in white plastic pill bottle with HBN powder. No tumbling media - just bullets and HBN powder. Place in vibratory tumbler while hot and tumble for 50-60 minutes. No problems thus far. Some batches look a little different than others, but they've all taken on a film of HBN. I've also used 1/8" round stainless steel pellets. Good results with them also. But I now use no media in my vibratory tumbler. Just hot bullets and HBN powder. I had a recent experience tumbling bullets with exposed lead tips - pointed soft points - which I didn't like. The Hornady Interlock bullets I tumbled with the exposed PSP lead tips turned my HBN powder and pill bottle a nasty toxic lead color. Not sure if the lead was preventing the coating of the bullets with HBN or not. The bullets looked different, but felt pretty slick. I wasn't sure so I tumbled them a second time. No difference. Puky lead coloring inside my white plastic bottle a second time. When I wiped the excess HBN powder off the tumbled bullets, my white bath towel was stained lead-colored. I won't be tumbling Hornady exposed lead tipped bullets any time soon. Now I had previously tumbled some Nosler Partitions with exposed lead tips and the lead on the Noslers didn't smear off and color my white pill bottle a blackish gray lead color. So as mentioned, not all bullets and brands of bullets are identical. [/QUOTE]
