@Unclenick, load was the rough load development at 100 yards back in mid December in mid 70's. Last Monday or Tuesday I did a sight in at 600 when it was in mid 40's then the match yesterday started at 8 am at around 30F increasing to low 40's by afternoon. I wasn't expecting much from the load but ended up at a solid 96% with only one flyer in the 8 ring that was my fault for shifting my weight with my finger on the trigger otherwise it was a pretty solid load considering the development, some mild wind conditions and mirage. Yes Virginia you can have mirage in cold weather. I looked through a Celestron sighting scope set at 60 power and it looked like a pinwheel, at 24 power through my rifle scope it was milder but visable
