Does anyone here shoot 6XC? I have a rifle coming from Masterpiece Arms and am new to 6XC. I plan on using Tubb's die set, 115 DTAC bullets, Peterson small primer brass, and Federal GMM primers (mix in some Winchester and CCI to see which works the best). I am not sure which powders to try. I have on hand; IMR4064, RL17, CFE223, Win748, Power Pro 2000MR, BLC-2, and I think H335.

Can anyone suggest a powder?
