P700w anyone know which way to turn screws for tune?

If I remember correctly, ccw raised the reg pressure. I would like to add that you don’t turn the reg screw. You move it very little at a time. It’s a tiny little thing with a small range. You will bypass it quickly if you aren’t careful. My stock reg didn’t stay in my gun long. When I started getting close to the velocity I was looking for, the reg just couldn’t do it. Huma set at 130b = problem solved. 
 
If you can get 700 with a 14.3 I would call it a day. If you want to have a switch caliber gun, you might not want to mess with your .177 transfer port. The high power .22 pistols have a TP that you can drop a .177 pellet into. If you drill yours out to squeak that last couple fps, you are going to have a transfer port bigger than your bore when you switch back to .177. Not good.
