[QUOTE="Veteran, post: 3005609, member: 118038"] I would also like to point out that you cannot expect tuning QL to match velocity over a really wide range of charge weights by varying burn rate to work. Burn rate is certainly not a linear curve with temperature as I have seen it go exponential. I don't believe it is linear with pressure either. So over a wide range of velocity and charge weights and for differing bullets, etc. its always gonna have to be recalibrated for the specific velocity and charge range you are in. Its a non linear function. Just works on small segments of the curve at a time. [/QUOTE]
