I remember when I used to do that with my defiant. You get less kick if you put the LPR a quarter turn past where it fully cocks and adjust the HPR for velocity. If you have to adjust the HPR too high then you up the dwell by 2 ms until you get the HPR in a good range.ah ok.
set the regulators to 0ish. air it up, set the hpr to around 230psi. then turnt he LPR in till teh bolt cocks and you hear a leak, back it out till the leak stops, yet the bolt stays cocked.
Now the fun begins, At this point it should be shooting, but no marker is the same so everyone has a different setting. An air effecient setup is a high HPR pressure and low dwell. A low kick setup is the opposite.
