bottle with a Hilpump? I am a big guy and kinda strong especially in the smell department.

ULTRA is 500cc
after you top up the most efficient way to go is, shoot one Magazine than top up again and so on, that way it gets you back to shooting in seconds.
when you done shoot her down to 100 BAR for storage
-
Pirate you are saying pump to 500 cc?
Oakey
-
No Pump to 200 BAR, shoot one Mag, pump back up to 200 BAR and so on.
when you decide to call it a day shoot down to 100 BAR for storage
500cc is the reservoir of the Ultra for comparison, I used to pump 2 of them beasts
-
Got ya Pirate. After every 10 rounds pump her back up. Then when I am ready to call it a day shoot her down to 100 bar. Makes life easier. Are their problems when a bottle is left at 200 bar?

You can leave all guns fully charged, in time, and I mean tiiiiiiime the high pressure might distort the valve resulting in loss of power, but the valve is easy to replace.
I just got in the habit of storing at 100 BAR, still there's lots of power left that if you need to pick up the gun to dispach something it will do the job
-
That was my concern Pirate.
Thanks Again

Lets see...takes about 45 pumps put in 1000psi (from 1K to 2K) on a 135cc Discovery. If the discovery volume was 3.56X as large (480cc's), that would be about 160 pumps per 1000psi.
Takes about 80 pumps to get an M-Rod's 215cc's up 1000psi (2K to 3K)....so if the M-rod had 2.23X as much volume, would need about 178 pumps.
Going to have to guess about 165-180 pump strokes per 1000psi. So the first time you fill from empty, it's going to take a lot of pumping.
-
They never send them empty, usually 100 BAR is in the gun already
-
I hope this Hilpump is more efficient then other pumps and easier to work with. I have heard good things about them.

LOL, those first pump strokes below 1000psi feel like no air is going in!! :o
Oakey, just pump, you will get used to it and build some muscles as well ;). Pumping is totally not funny in the summer. >:( >:(

That's how it goes Tiger.

hi, i just recently bought my first pcp and i am waiting for it to come in . anyways can someone explain to me what 100 bar or 200 bar means ? i thought when you fill your guns with air it goes by psi like 3000 psi or 2500 psi . if bar is calculated into psi what would 3000 psi be in bar terms ? if at all they are related . thank you ...rob

Bought 2 scuba tanks 80 CF Aluminum. Hill MKIII pump sits in closet. Top tanks off every few weeks ($6). Shoot 200-350 a week. Always fill from 1500 - 2800 with one tank and top off to 3000 psi with other. Takes about 20 secs and no pumps. ;)

Rob, 200 bar is just less than 3000 psi. 100 bar is about 1500 psi. Pumps usually have both scales on them. Guns that have gauges may only have one scale on them.

Bar is another unit of pressure. 1 bar = 14.5 psi = 0.99 atm = 100,000 pascals = 10 N/cm^2 = 750 torr and so on. So, 100 bar = 100 x 14.5 psi = 1,450 psi. 200 bar is 2900 psi (close enough for most folks to 3,000 psi).
There are many ways to express the same amount of something in different units, depending on what country you are from (i.e. what standards are taught in your country), what field of science or engineering one might participate in, etc.

Rob, 200 mbar is just less than 3000 psi. 100 mbar is about 1500 psi. Pumps usually have both scales on them. Guns that have gauges may only have one scale on them.

Remove the "m" from your bar expressions and you are correct... 1 mbar = 1/1000 bar.
-
thank you guys for explaining it to me . now i understand it clearly ..
-
Me too Rob. I get it now.
Thanks

hehe sorry. will fix. I am use to weather crapola.

I have to face it am in love with SMALL VOLUME pcps's. If it is under 200CC's in volume, know I can fill it from the bottom to the top of the sweep spot in one (50 pump stoke or less) sitting.
As a pump filler, I stay away from large volume PCP's, being "happy" with the guns 180cc's or smaller.
-
Now that's efficient thinking Ribbon. But The Last-Ed-Tiger told me I can get me some Muscles Pumping up my 480cc tank and stay in shape too. I don't mind the pumping. I like big muscles. When the pump is cooling down I will just go into the shed and beat the pulp outta my MMA bag!

+60 years, 5' 10", 170 pounds...no problem hand pumping any of the PCPs I own. But they range from about 380cc's to as small as 30cc''s. Am a "sucker" for anything "good" under 200-180CC's.
That is opposite the current trends in airguns...currently, large air volumes a "in" and small volumes are "out".
-
You are right Ribbon I was on another site last night and the low fill used PCP's are going super cheap. These guns cost big bucks a few years back.
I am 46 and need to keep pumping.

Pump filling is the best way to end up with a full gun, have fun shooting, and avoid "man-breasts" in your old age. Nothing quite as unappealing as a set of "c" cups on an old guy.
But dude...no way I'm willingly going to pump-fill 480cc's to 3K.
Can think of myself as "skinny"...so if this "crusty"old guy can pump fill a PCp, a "young-un" like you should have no problem.
