anybody tried Unique and PC lead in 300 Blackout?

[mavracer]

Was wanting to try this combination and see how it worked and wondered if anybody had tried it.

Was gonna use MBC 165gr coated bullets and enough Unique to make 1000 fps.

Sounds completely doable, but I haven't tried it.

Don't expect unique to cycle if its an AR.

But the PC lead will work...

098, what cast bullet is it? Feed Ok in AR?

Lee 311-155 sized to 309.
Worked great!
