[QUOTE="JTB, post: 1308545, member: 97196"] I had never bought in to the bullet coating business until I installed a new barrel that lost accuracy after 15 shots no matter what break-in procedure I followed due to copper fouling. Decided to give the HBN a try and the problem went away almost instantly. The system I use for coating amounts to an old peanut butter plastic bottle containing stainless steel jeweler's tumbling media and a teaspoonful of HBN. Just load the bottle with 100 170gr 270 EOLs and set it in the vibratory tumbler for about 30 minutes. I then separate out the bullets and place them in an old tube sock and rock them back and forth in the sock a few times; they come out perfect. I found I needed to cover the tumbler lid hold-down screw with some gas line to keep the peanut butter bottle from wearing in the middle as it rotated. Also wrap the bottle lid with electal tape to keep it secure and to smooth the lid edge. Without the tape it will begin to wear a groove in the tumbler bowel where it rotates against it. I only coat bullets for this specific barrel but the HBN solved my problem. [/QUOTE]
