Berger 22 cal

[petepeterson]

I have 6 boxes of older berger 22cal 50 gr match grade bullets, 3 have a pn of 22006 and 4 have a pn of 22406. They all say made with j4 jackets. The 22006 have a cooper looking jacket and the 22406 don't look like they have a jacket at all. (see pics) Anyone have any thoughts on this?

Are we asking about the MoS2 coating?

Sent you a pm but those black looking ones are moly coated.

 

[petepeterson]

Thanks for the reply, not sure what MoS2 is, is that moly coating

 

[OKyote73]

Yes...

 

[petepeterson]

Thanks a lot for the help.

Sorry @petepeterson MoS2 is shorthand for Molybdenum Disulfide.

It is a solid lubricant that is transferred to the bullet from a powdered form using impingement burnishing methods.

That's OK thanks for getting back to me, I am finding this isn't too popular anymore.
