Thank you, PCP - I also found your thread on the air rifle forum - I had forgotten about that.
At the lower allowable power, you should do very well with your DR.
27fps is very good for a PCP considering you started full.
Well done.

This is a very precise & meticulous game, working with minute detail changes in shape and diameter of orifices, making huge differences when dealing with pressures such as 3,000psi.
