•Excellent Lubricating Properties due to low Coefficient of Friction at 0.15 to 0.70
•Good Chemical Inertness
•Electrical Insulator
•Thermal Conductor (result: better heat dissipation)
•High Temperature Stability, 1000o C in Air, 1400o C in Vacuum and 1800o C in Inert gas
•Low Thermal Expansion
•Low Dielectric Constant
•High Load bearing properties
•Non-Wetting: hBN is not wetted by Glasses, Salts and (most) metals, therefore it provides strong resistance to chemical attack Easy Machineability (in hot pressed state). Complex shapes can be machined from hot pressed structure.

0.4oz in tube.

How much is that?  It’s about a 1/3 cup.  At 3 grains per hundred rounds, a reloader  should have enough to give you significant data.

There are a problem with the BSA Wheels. I have very limited amount of sets left that are machinable that do not wobble.
Matched inner bore will not be available. #15 molds are no longer premium wheels. Please watch this video: https://youtu.be/OGlZlB_h7a4

Just to be clear, I do not sell wheels that wobble. I will not sell junk wheels. I rather have no sales, than have my name associated with junk wheels.
The wheels that you see in the video are thrown away. They are not used.

BSA is aware of the problems, I am the second person to file formal complaint. Just remember I buy from same place you do.
I have been instructed by national scoutshop not to place another order for wheels. So at some point I will run out. I have no special inside line for a better product.
