What are you guys getting mine is about 26 fpe with hammer spring adjusted to max if i adjust it more it won't cock.Then i release hammer spring one turn back and i am getting 810fps with Jsb monster pellets.
I have mine shooting 13.43's at 850 and 10.34's at 940. I don't remember how many turns back from max. I think it is one and a half. I started at two and shot over the chrony until the E.S. started to widen then backed off a bit. It comes off the reg. about 110 to 115 with a slow drop off. At max hst there is too much spring for the set pressure and E.S. is bad.
Today i tested both regular monsters and monster redesigned with bad results at 51 m. Hades also didn't do well.I will make another post of my pellet testing results.
Having recently set up a STD Vet .177 for FT work and wanting it set up a tad hot ( 10.3 @ 920 ) it took setting the Reg a tad higher to get it so the velocity was stable coming off reg as well any reg creep stability. At this setting Monster 13.43.s running @ 845 or so.
In my fooling around it became pretty obvious leaning on the power took a LOT more air and efficiency crashed really fast.
Motorhead thanks for your reply.What kind of accuracy did you get at that setting. Today i tested 10.34 gr at 925 and the accuracy was not as good as at 870 fps. Also how accurate is with 13.43?
