[QUOTE="Broz, post: 1106005, member: 7503"] Ok , its 2:15 am and I am back. I re-tumbled the bullets that didn't coat for another 3 hours. Only change was to add the same mixed bunch of stainless media back in that I was using before, The bullets cleaned up and coated well now. They are slick, smooth and tips look great too. All I will do from here is to hand polish / wipe them down and re-drill the hollow points with my .027" wire drill in .300" deep. Happy now!! :) This must have to do with tumbler vs virbrate. I got the 3 hrs Paul from the instructions that came with the Bullet Coatings kit. It states "2 hrs / 100 bullets "Vibrate / Tumble" and inspect". "If not to your satisfaction go an additional 1/2 hr at a time till you like what you see" I thought 3 hrs was a good number for the amount of bullets and their size and weight. I Just put in another 120 with the media and same amount of HBN from the same lot of bullets to see how they look in 3 more hours. One big observation I can offer is I am using a little over 3 times as much HBN now as the "Bullet Coatings" instructions state to use per 100. This took some testing since they make no adjustments for bullet weights. I feel they should do a better job with their instructions, or at least return the phone messages I left them. Obviously it takes more HBN to coat 100 Berger 300 gr bullets than 100 Berger 55 gr bullets. What I saw was, by using less HBN in the bottle of 100, was the bullets took on a darker bronze look. The less HBN used the darker they came out. I increased the amount of HBN each time and now I am getting only a slight discoloration of the bullets. Just a little bit of a milky color to them now. But coverage is good, very even and they are slick and smooth. I should also add that even on the darker bullets with less HBN used the coverage was good too. Just way darker in color. Thanks for the help guys. I didn't mean to take over your thread. I appreciate your help and will let you know hoe this next batch of 120 come out in the morning. Jeff [/QUOTE]
