BL-C2 or WC 844? That's what I've read on some of the black gun forums anyhow. Ask Kevin Thomas? from Lapua USA. He seems to know a lot about that stuff and has helped me with a few questions.

The answer is the new WC842.... Supposed to be similar (not identical) to CPF223

Does anyone know the charge weight of the MK318 using WC842 powder ?

WC 842 was made just for the M4/SCAR
