So which powders are you guys using in 6mm Creedmoor? Using bullet weights of 105gr - 110gr I'm planning on trying H-4350 and RL-16 first. Anyone using these combo's? Or which other powders? The brass that I'm trying with this combo is Peterson SRP. Waiting for Lapuas first production run to come out and then I'll switch. I have to say that the Peterson brass does look nice and comes in a 50rd plastic box well contained for shipping and for keeping loaded ammo in. Lapua does also come in a plastic box. Both come nicely annealed too.
