Hello all. My 6.5 Creedmoor shoots the Barnes 127 grain factory like a dream. Excellent velocity, single digit SD, and .5 to .75 MOA groups. Do any of you fine folks happen to know if they are using temperature stable powders? I could cool some rounds and leave others to warm in the sun, but that is where the only thing I don’t love about the ammo comes into play. Cost. Can anybody help me out?
