Re: Chrony F1 stand
Any photo tripod should work.. I do most of my shooting prone, so I just set it up on the box or laying it on the ground. The JOBY from REI.com might work well since it's adjustable.
I have to echo victor. It's probably not the most accurate chrony in the world. Take good notes on your velocities but let your down range results tell you the real truth about your loads. Use it give you an idea of where your avg. velocity is but I wouldn't trust it to give you accurate ES or SD values.
