Clyde,
I know it has been a while but as June turned into August I haven't spend more than an hour at the indoor range where I usually test with my chronograph. Most of my shooting has been at a large outdoor range North of Boston where I can spend most of the day here is the link

This place has everything including a Cowboy Action village, a 300 yard high power, and a seperate class 3 range!
