Have been trying these bullets in my ROCK, 47 grains of Varget shot five into 0.287" at 100 yards today. Have several groups in the 0.3's. Not sure if that is good enough for long range shooting but will give them a try Jerry Teo will probably agree, these bullets fly nice. Back to the big green reloading machine. My PRO-2000 makes this ammo and it shoots decent, no handjobbing involved like trimming, primer pockets etc. This is twice fired Norma brass, Win. primers, and thrown powder charges. My friend and I can crank five boxes in 20 minutes, gives us more time to shoot steel. Nothing against doing the accuracy stuff to the brass etc, but I am happy with the ammo this machine is producing.
