[QUOTE="Kevin Thomas, post: 341470, member: 15748"] Hey Guys, Since I haven't seen anyone else mention this I thought I might chime in with a thought. Since we're talking about a major change in POI between 32 degrees and 78 degrees, everyone seems to have focused on the burn rate, ignition and velocity of the load itself, while leaving the temp itself out of the conversation. I'm sure you guys know this, but cold dry air is much denser than warmer more humid air. At these sorts of distances, it makes a significant difference and has to be taken into account. My guess here would be 1) atmospheric differences first, 2) powder or velocity variations second. Kevin Thomas Lapua USA [/QUOTE]
