Firstly chronographing went well. Diablo+ 150gn field tips which I assume is 400 grains. 364fps average with F-1 Shooting Chrony. I havent done the math but assume that is close to the right energy levels?
First shot was about 6 inches low and 6 inches right. Adjusted it up to the bullseye with a few more shots, using the one arrow for everything.
Then decided to do a 3 shot group with that arrow and 2 other arrows. 2.5" group at 40 yards....however the POI was now 5" low and 4" to the left.

I notice the string had lengthened during the shooting, brace height had changed from about 1/2" to 1/4", would that account for it? Scope issues? I had to pack it in due to rain but will take it out on Sunday and try again.
