Just Google, coated bullet test done by the USAF. You'll see the link entitled Form approved report documentation page OMB no.0704-0188.I don't recall reading it. Have a link?

I'm not sure I agree with their assumption that lower friction produces higher velocity. Clean a barrel and the first shot is usually lower (lower friction = lower pressure = lower velocity).
Normal cleaning routine.Well, I just got off the phone ordering some from D. Tubb. I still have some questions on how to clean the barrel after it's been "seasoned" with the HBN.
Please remember that IME the crux of the procedure of coating projectiles with HBN is temperature. In my procedure, I heat the ss bbs and the projectiles slowly in the oven to a point where you can touch them and hold them but just. Then I put the lot together and tumble them straight away. This info might save you time and effort. Any more info that I know that anyone needs, I'll be happy share with everyone.Curious to see what experience people have had with HBN coating bullets. What are some of the benefits and drawbacks? What kind of application were you using it in?
There is an easier way. Just get an empty plastic coffee jar, put the HBN, bullets and BB's in the jar, screw the lid on, take a towel and some duct tape and wrap the towel around the jar and wrap the towel with a little duct tape, throw the SOB in a clothes dryer, set it on medium heat for about a hour. This way the bullets stay warm when they are getting impacted.Please remember that IME the crux of the procedure of coating projectiles with HBN is temperature.

I have done the same using the Tubbs' System jar and about 200 140's without BB's. I wrapped it in 'two turns' of 2" foam rubber, tied the ends with cord, and off into the dryer with several large towels at medium heat for 40-45min. If I fill the bottle nearly full with bullets no meplat damage will occur. Mine feel and look the same as Tubbs' HBN coated 115 DTACs that I purchased precoated.There is an easier way.

I beg to differ. I can pick up a cold tumbled bullet and one that was done in the dryer and I can feel the difference between the two.Heating the bullets/media is a waste of time and completely unnecessary.
Other than the the warm feeling from the dryer tumbled bullets, what difference do you feel, Jim?I beg to differ. I can pick up a cold tumbled bullet and one that was done in the dryer and I can feel the difference between the two.
The dryer impacted one feel more slippery in my fingers than the other method that I use to use. It's like describing how a B&A trigger feels vs a Jewell. Your finger can differentiate between the 2 just by feel.Other than the the warm feeling from the dryer tumbled bullets, what difference do you feel, Jim?
I have a grasp gauge. My grasp gauge does not measure in tensions or pounds. It measures feelHee, Hee, Hee! Is that "slipperyer" feeling in tensions or pounds? fguffey wants to know.
