This will be the last entry for a while. They just closed our rifle/pistol range, the skeet and trap ranges, our indoor and outdoor archery ranges, and the indoor air pistol/air rifle range because of the corona virus.
Even though the rifle/pistol range is an outdoor range with plenty of space to maintain separation, a majority of RSOs, who are mostly geezers like me, didn't want to be exposed. I can understand that, especially given the panic about the virus in Northern Virginia and in Washington DC.
The following data is from my last range visit on the 16th, the day before they closed the ranges.
Here is my most recent data.
Winds in the early morning were from 3 to 5 mph with temperatures rising pretty rapidly from 33 to 46 from 8 AM to 11 AM. The temps had risen to 36 degrees before I actually put the first round down range because I spent some time BSing with the RSO - a good friend.
I shot VV N140 powder, a temperature sensitive powder that I had loaded from 33 to 46 degrees based on my prediction of the temperatures over the time I intended to shoot. Even with the later than planned start, my predicted temperature was never off by more than 3 degrees from what I loaded for.
