I looked but can't find anything on tuning a Renegade....Mine shoots the 177 RDM's at only 750 and the 10.3's at 865....Seemed pretty low for the RDM's
My hunch is they would be similar to tuning a Huntsman, tuneable but not exactly user friendly in changing settings. There are a few You Tubes on those. You might want to PM Arzrover, I am sure he would have some wisdom on the matter.
