Is there a Downside/Drawback to using Moly bullets

[Litehiker]

THE best coating for rifle bullets is HBN powder (Hexagonal boron nitride). There is a great YouTube video about this on Rifles Only and the Tubbs web site as well. Tubbws sells many cartridges with bullets coated in HBN but a tumbler and some powder will do you for starters.

Essentially HBN coating is what moly coating was supposed to be - but wasn't.
But beware, you will likely need to INCREASE YOUR POWDER CHARGE to get back up to your "accuracy velocity" because HBN is so damned slippery that the bullets get out the barrel before enough pressure can be built up to get the velocity you need.
The Lord giveth and the Lord taketh away. jus'sayin'...

Yup - and that's just one of the issues that drives the importance of bullet crimping with the Lee FCD!
