[QUOTE="Cold Trigger Finger, post: 1090497, member: 56732"] I just recently got set up to coat bullets with HBN. I use acetone to clean the bullets. Dry them on paper towels. Put them in Mason 1/2 pint jars and put 1/4 teaspoon hbn in on top of the bullets. Put the lids on TIGHT and tumble in a Harbor Freight double drum rock polisher. And tumble for 2 hours. The bullets come out fully coated and I polish them in 2 cotton socks. All I've done so far are 6.5 bullets. Did a box of 130 gr Barnes TSX and almost 200 140 gr Nosler CCs. I've got some of the 140s loaded to shoot in my 6.5 Creedmoor. I have both uncoated and coated 140CCs loaded with the same powder charge from the same bottle of powder. Brass is from the same box of new brass. Same primers. Same oal. I haven't shot them yet. Just got back home but hope to this week. I'll report back with my findings. My load is 45.3 gr Superformance. Barrel length is 18.6" I'm definitely interested in the velocity but as this is a hunting rifle that I want to use for lr hunting. I'm most concerned with the cold bore shot being in the group. [/QUOTE]
