Other than some minor tweaks to my VP when I got it I really hadn't made any changes to it. I never even thought about touching the micro adjustment of the hammer spring either.
With it being cold with 30 mph winds the last few days and after watching AEAC video and going through this thread.

I decided to switch from the pellet port to the slug port and start from scratch just for the experience.
Initial tune was pellet port, 2nd reg at 120 bar, wheel at 7 and upon checking the micro adjustment was 3/4 turn ccw. I was getting 893 with 34 gr JSB's..
The thing that got my attention in the above post was the possibility of achieving the same speeds with lower pressure/hammer.
I flipped the port, lowered the 2nd reg to 105 bar, wheel at 6, micro cw all the way. Low 800's.
After working my way through a few things with the hammer spring I ended up with slug port, 2nd reg at 112, wheel at 7, micro adjustment at 1/2 turn ccw.
30 shot string resulted in
Avg FPS 910.13
Max spread of 11
SD 3.54
I was very pleased with this but......decided since it's simple to turn the wheel down to 6
30 shot string resulted in
Avg FPS 908.93
Max Spread of 7
SD 2.94
Going down to 6 was a large FPS drop.
I originally was going for an FPS of around 900 but overshot my reg adjustment going from 105 to 110 and after a few dry fires it moved up from 110 to 112 where it has stayed.
If this wind ever dies down I'll do that final confirmation and sight it in to check it's grouping. I also want to see how much improvement there is in shot count per fill.
