what do you guys have your low pressures set on? when i put it at 150 it seems way too slow, when its around 210 is where i get 270 fps. i dunno if i should crank up my high pressure or what

then leave it at 210-215. Blowbacks won't ever get Angel-low psi...yer good where yer at.

I had my LP Rodeo running at 250psi/285fps and it was pretty consistent. Play with the pressure and go as low as you can with still being able to re cock the bolt and getting decent FPS. Then turn it up a little so you wont have re cocking issues if the pressure drops during play.

if He's running 210 psi and a consistant 270fps...that's good considering he's only 10 psi higher than my uber modded Esprit was at 279fps...he really can't ask for much more...

210+ in the lp? when i do that the bolt doesnt return if i get a high ROF

oh...LOL...sorry...yeah...raise your pressure 15-25 psi at a time until recocking issues stop.

do u mean lower?
04-27-2006, 06:31 PM
i think 210 is a little high for EP marker... Maybe turn it down... or adjust your LP cause i know BKOs (Primal essitialy the same thing) run at like 180 for 300 fps ...
I havent gotten my primal in yet.... so i realy cant offer exact information yet but i will soon.

my primal is not working well again. it shoots but barely. i cant turn the lpr past 200. when the chamber is at like 180 it wont cock back. my hpr is screwed up at the bottom. if anyone has any ideas that would be very apprciated. its either fix it or send it back and hopefully get a new one from kingman...i still ahve the warentee card here and i got it in feb. whever i do im gonna sell this pos. it always breaks down and isnt worth the price tag.

What do you have your HPR (high pressure reg) set on? You need to put it at whatever the optimal pressure for the Primal is, then back your LPR (low pressure reg) out until it leaks. Then up the pressure in your LPR until the hissing stops.
Fire your gun several times, listening for a leak. If it still leaks when you shoot it, raise it up a quarter turn more and fire your gun several times again, again, listening for leaks. Keep doing it until the hissing stops. Once it stops leaking, turn the LPR up a quarter turn then lock it down. Check your speed over a chrono. If it's too high, lower the HPR input and do the whole process all over again.
Any time you adjust your HPR, you'll need to adjust your LPR. It's just a hassle, but once you get it locked in, you should be ok.

my hpr is screwed up.it doesnt really move much at all when i turn teh screw and im just gonna take it up to my local shop and tell them to put a new one on and fix the problem

That could be your problem. Try getting a Torpedo or some other regulator. I bet you would see your problem fixed.

what pressures do u run ur hpr and lpr at?
05-04-2006, 02:35 PM
I run my lpr at 115psi and I use the chrono readings to either turn up or down my hpr.
