jumpy reg

seanhockey13 (Banned) · 02-13-2011, 07:06 PM

hey guys so i traded for my g6r and i set the LP to about 65 ish and the hpr is around 150 id say. i wanted my gun at about 285 but the reg was +- 15 or more so i changed the oring in the reg and it and it seemed to help a little but still jumpy as heck! any ideas what to do?

how much grease on the o ring in the reg?

also any good ideas for the LPR setting and HPR settings you all have had.(looking to crono at 285)

Are you using good paint and a good paint/bore match?
Whats your dwell at?
Are you using the correct lube?

idk i just traded or it. But today i shot like 2 cases through it or so and i saw how jumpy it was so i had to spare and i decided to change the o ring in the reg and after i did that i had to up my HPR cause it droped down to sub 230s

just a thin amount of lube. enough to feel it but barely see it. How much is on there now?

too much lol xD

Super69ur · 02-13-2011, 08:16 PM

Get all that excess lube off there! In the LPR and HPR. That and shooting more paint through it should help! GL

All guns are different and require different needs.

If your gun came with a card, it will have the stock pressures and what it chrono'd at, start with that and mess with it from there.

it did but now it has the slp reg

gamer565 · 02-13-2011, 08:45 PM

And?

Set your regs to pressure on card and go from there.

K all try that

Up your LPR to 70.

wont that make my gun kick more?? I thought i was suppose to set my gun the lowest lpr setting it can handle then just tweek the HPR tell the volicity you want it met. DOes the LPR have any effect on the volicity? i thought it controlled how the rammer. im seeking a pretty smooth shot

efficiency through consistency. normally lpr is higher but if the gun shoots in a good window of FPS over the chrono. then dont worry about it.

Smooth shot is useless if you're consistency is ****. You cannot say "low LPR = bestest thing evar! Why doesn't my gun work with my LPR at 20psi?" because going too low is going to cause problems with cycling and consistency. Keep your gun stock until you put 5-10 cases in it and then you can start tweaking, but even still you should probably not go THAT much lower than 70. It is possible to get a smoother shot via means other than the LPR so don't get fixated on needing to run your LPR way out of spec. Try upping your dwell a bit too. That will decrease efficiency a little bit but it will lower the force on the internals (Impulse = Force x Time, higher time = lower force) and give you a smoother shot.

When you say "the reg is jumpy" do you mean your velocity is sporadic or your pressures are changing from shot to shot? Your velocity being sporadic is likely due to your LPR being out of spec. Pressures being sporadic means your reg needs to be cleaned (which you said you already did).

ok thx, i traded for this gun so i dont know how much paint has been through it but it does have the LP poppet. so when i go to play next ill set the LPR to 70. then do i just go to the crono and tweek the HPR tell it is at what i need.
also what should i up my dwell too as of now it is stock.
sorry my velocity is sporadic

Add one or two milliseconds to it. Especially in cold weather this can help with consistency as well.

seanhockey13 (Banned) · 02-14-2011, 06:36 PM

ok so ill up the dwell to 7 or 8 and then ill set the LPR to 70 and take to the crono and set it to what i need
