[QUOTE="BrentM, post: 885909, member: 61747"] MV is FPS/per degree. If that is what you are doing then it likely is causing your issue. As noted by the last poster if you use 1FPS/degree a 20 degree outside temp change will give you a 20 FPS variance. That is actually quite a lot. You will need to chono or dope this to find out the real affect. Most people input something like .25 to .5 for fps/degree. Gunwerks has a video that shows the difference in sensitive vs extreme powder variances in FPS. I think the did 32F and 90F or something like that. I use extreme powders and have virtually no variance from 10f to 90f. [/QUOTE]
