raw 500 mk11

My TM 1000 is in .177. Currently with what the regulator is set at (I think around 115 bar) and with the HS right int the middle, it's shooting the 13 g's at 770 fps with about a 1.75 SD and an ES for one card (25 - 27 shots) of about 10 fps. This is from memory. 

When I turned up the hammer spring, it was shooting the 13 g's at around 830 fps, and the SD went up to around 2.25. I'm going to play around with it some more to see how fast it will shoot the 13 g's with a SD below 2. Then I'll shoot groups with about a 25fps difference between groups and see what the most accurate speed is. Then do that with the other weight pellets as well. This is the fun part!!
 
By right in the middle, I mean the way it came from RAW. the screw head/plate is flush with the breech block. I've turned it clockwise so that the velocity increases and the head/plate becomes recessed. I haven't tried it yet, but I'm assuming that I can turn it counter clock wise so that the velocity decreases and the screw head/plate will stick out a bit from the back of the breech block. I'll let you know if this is so. 

I didn't do any testing with ES and SD when it was new. Just looked at velocity, so I can't compare. It's still pretty new. Have only had it since December and probably have only put 500 rounds through it. So, don't know if this is enough to break in the regulator.
