I shot two, three shot groups. The second was slightly larger .274 inches. Average velocity from my chrony was 3,156 fps, 200 grain Nos. Accubond, 92grns of RL-25, 26 inch tube.
The Barnes 180 grain, TTSX, pushed by 100 grains of Retumbo, did much better too. They grouped .320 and .332 inches, velocity was an amazing 3,502 fps. I will be ordering custom (CDS) dials for each load.
