Shot at the public range yesterday, which I hate, and between the compressed time to check targets etc and not being able to correct issues if they occurred with the crony I kept it really close so I could reach it if I had to.  Well every first round from a string would read about 1000fps slower than all the other rounds.  I was shooting suppressed AR10 and think something about the suppressor is the root cause but the suppressor was also why I was comfortable keeping it close.  Can anyone tell me what the issue was?  I was using a Crony F-1.

Got be out of muzzle blast range.

I do all my testing at 15 feet.

The suppressor will direct almost all the gas straight forward, so you need to make sure your chrony is 15-20ft from the tip of the gun.
