I was so happy with my results earlier this week, I went back to do a little more shooting.
The Blackarc Munitions 110 Gr Barnes black tip makes about 2,170 FPS out of an 8" Craddock Precision stainless barrel. The same gun pushes a SIG 120 gr copper round that is a specific short barrel load, so this is picking up about 75 FPS. I've found the SIG load to be mediocre in accuracy, but good terminal performance on pigs. As a practical matter, the 8" is a 100 yard gun at the most as set up anyway. With that said, I have some of the Phantom 85 gr headed this way to see how fast the 8" pushes that - but I think the 12.5" and Blackarc are destined to go kill a bunch of pigs.
The AAC / ACOG + SRO / Blackarc continues to to make me very, very happy regarding accuracy and reticle calibration. The large circle with the "2" is with the SRO, the "4" is with the ACOG, both at 100 off a tripod - then I went to 300 as the other day I hit 200 and 400 with great results - also dead on at 300 as the drops would indicate. At that distance, the diamond is about covering the torso, but it makes clear the reason the ACOG revolutionized combat effectiveness.
