Just picked up a TRG in 6mm Creedmoor, I have everything I need to reload for it now, just wondering what powder charge to start off with? Everyone I see is using H4350, and I have a few lbs of RL-15 laying around and would like to try that before buying any more, lol. Anyone use this powder with the 6mm, or someone more experienced know a safe starting point?
