I have been trying to work up a load with several different lots of powders in my 338-06 and 180 gr BT.RL15-2800FPS,4064-2820FPS,varget-2800,VVN550-2870FPS but when I tried BL-C2 I got 2950 which is what the books claim I should get.My Question is some think the powder burns too dirty and I don't know if it is temperature stable.Our hunting temperatures during season run from the mid 40's to upper 80's on most days.Give me some thoughts on this guys cause I can shoot the NP 2770 W/62GR of 4350.Just don't understand why I can't get better velocities with max loads from the supposed favorites and the 180's.Please help me as I am getting concerned.

P.S.I have not tried IMR 4320...YET. powdr
