I got out to shoot a bit Saturday with the grandsons. I didn't have enough time to do a lot of my stuff as I was getting them set up with their 10/22's and new Christmas scopes. I had them ringing 4" steel from 100yds off my portable bench.
At any rate, no chrono data, but I sent some down the tube. I have a Labradar, but it was right around 30-32 degrees out and enough fog/mist in the air that my bench top started to ice over. What I can report is that the 31.6 gr max loads with 87 Vmax seem to cycle my Cobalt pretty reliably. First shot single fed on an empty mag locked open after the shot so I stacked them in and cycled through the rest. I believe that the final round did not lock open, but they all fed.
