I was out shooting the impact today and when my bottle pressure gets down to about 175 bar air starts to leak when I open the bolt, from the barrel. If I recharge to 250 bar it doesn't leak until it gets back down to 175. Anybody have this happen before?

In general when the air is leaking from the barrel the problem is connected with the derlin on the valve rod and the valve seat .The difference in your case is that is stop leaking when you refill at 250 bar.
If your leak continue try to check if all the threads on valve rod are tight (including and the hammer seat which is the easies to check).
If everything is tight in its position you need to check if you have scratches on the valve rod derlin or the steel valve seat in valve housing .
But because your leak is,appearing only in 175 bars,and it stops when you refill I recommend you to not disassemble the gun deeper if you don't feel comfortable with this.Try first to adjust counterclockwise the hammer spring screw as Odoyle suggests you or just move the power wheel in lower position than your max and repeat shooting to see whats happening when the pressure drops around 175 bar.

Thanks for the help. I backed out the HSP screw until I was just getting movement on the HSP block with the power wheel from min to #1 setting. No more leaking. This all started when I installed the slug power kit. I am assuming that the hammer weight washers added preload to what I already had dialed in.
