[QUOTE="406precision, post: 879855, member: 69335"] Although its possible some of it could be scope issues. I would lean towards barometric pressure and temp variance if it were me. We usually try and do our load work in hunting conditions if at all possible and verify drops at average high and low temps like 35 and 70 if that makes sense. you'll definitely see a difference in point of impact. I don't know if you keep a log book or not, but if your shooting lon range you should keep one for every rifle that way you can record the temp, baro pressure, elevation, and wind for each shooting session and the results. It is really helpful to look back after a few trips to the range and compare notes and make adjustments based on an average of your data collection. It is also very helpful to look back at where each shot landed and to use that to correct your form and or drop charts.. [/QUOTE]
