[QUOTE="SHRTSHTR, post: 1105791, member: 12514"] Paul, I also watched the David Tubbs video again and do not think he is using any media when vibratory tumbling his bullets, as you had suggested. As you know I used the bulletcoating.com kit with assorted media in SS. The media pinged and dinged the 300g Bergers pretty good. Also deformed the Meplat and left small dents in Meplat face. Pretty easy to see how crappy the jackets looked after looking at them closely with a 35 power microscope. I also used our Profilometer to check surface finish before and after HBN and tumbling media. Lost 4 point after tumbling bullets with media. Bullets were slippery but surface finish was rougher. Bad Mojo in my books. Took 100 300g bullets, pointed and trimmed Meplat and redrilled hole. Cleaned bullets in Acetone and let air dry. Preheated oven to 180 degrees and heat bullets and pill bottle for 30 minutes (did not melt plastic). I then used the big spoon supplied from bullet coating and added to bullets. Vibratory tumbled for 45 minutes and after shaking bullets in a strainer, I toweled of any excess HBN from bullets. Very happy with this method, no damage or pinging whatsoever! Bullets are slick and ready to load. Thanks for your help Paul! Yes, I did dump all the SS media in the trash can :cool: Ray [/QUOTE]
