I also have good velocities with IMR 4350 in two 6.5 Creedmoors. Around 2800 with 143 ELDX from two TC Compas rifles. I have questioned my chronograph because it seems too high. load is 0.3 below Hodgdon max.I use IMR 4350 41.5 grains 140 A Max good accuracy decent velocity. just under 2900fps. I no not a lot os fans of this powder here but works for many loads I've developed.
