At 4x speed, watch me load 49 rounds with the AutoTrickler and new AutoThrow, which will be shipping August 2017. Loaded and seated in under 20 minutes. I'm using 44.5 Varget with KP Ballistics' new 200 grain 308 bullet and BR2 primers. This bullet has a G7 BC of 0.357 making it significantly better than the 200-20x and it shoots like a laser beam at 1000 meters. No more 185 Juggernauts in my future... autotrickler.com kpballistics.com
