RL 15 vs. N540

[Gman]

Does anyone know which of these two powders tends to give a higher velocity ? This would be in a 6BR, 28" bbl., shooting 105-108 projectiles.

Gman, According to some literature that Robert Whitley has on his 6mmAR.com web-site, RL-15 and VV-N540 is really close. I don't know if he could tell you which will give the higher velocity but in the 6mmAR he says that RL-15 is giving some of the best accuracy and velocities. Robert is a real nice guy and would share his knowledge with you I'm sure. Bill
