John,

Just finished it...very good read over all. Thanks. I'm especially excited with the info on the 308 win, as I just traded for my first and I'm excited to get it put together to shoot. Any input on AR-Comp in regards its temp stability? I'm having a hard time finding everyone's favorite pixy dust #AR2208 (AKA Varget) and often see AR-Comp around here. Maybe a PM with more info would be best.
Thanks, and happy new years!
