  I got a 20 pound tank at an estate sale a year or so ago.  The thing is 50 years old, apparently once belonged to Coca Cola.  Gave five bucks for it.  Had it tested and filled, no more short fills on my paintball tanks at Academy!

Pretty sure Dick’s short-filled my new tank. Went dry quick. Going to weigh it b4 and after, next time.

Terry, I don't know the internal volume of a 114 tube, and I no longer have one.... If you can give me the ID and the inside length, from the back of the fill fitting to the front of the valve, I can calculate that for you.... A Disco, with an internal volume of 135 cc can safely hold 90 grams of CO2....

I got a Co2 charger from Baker.  It let's you use a 12 gram Co2 cartridge to fill the old crosmans.   it works well on my 111 and 116.

My bet is that the OP is filling with gas, not liquid CO2.... You should get more shots by bulk filling....

I had a 114 once, and IIRC I drilled through the brass CO2 fill fitting and threaded it for a male Foster.... then bulk filled from a 20 oz. CO2 cylinder through a standard ASA fitting with female Foster.... I had to invert the tank to fill the gun....

If you warm the supply tank and chill the gun, you have a chance of overfilling the gun with CO2.... That can be VERY dangerous, because when the gun warms up the pressure can skyrocket.... high enough to blow a 3K burst disc on a CO2 tank that is overfilled....  :o …. CO2 should always be filled by WEIGHT, not by volume.... The correct weigh of CO2 for a 100% fill is 7/18 oz. per CI.... which works out to 2/3 gram per cc.... For each 30 cc of tube volume, that means 20 grams of CO2....

  Bob, would you mind checking my math? (Never was my strongest subject.)  Measured the internal space in my Sheridan F with Mac1 bulk adapter.  .75" x 15.25".  By my calculation, this is 110.4 cc...?  A max fill would be 72 grams?  Filled yesterday and got somewhere close to 90 grams in it, dry fired till it was down to about 80.  Probably better dry fire some more.

  I've always dry fired my bulk fill guns down to empty before refilling.  Just assumed this was how to do it, since my 12 gram guns are always empty before recharging.  Now I know this is not necessary.  Experimenting with using ice packs against the tube, wrapped in a towel, to chill it for about 15 minutes.  Seems to work pretty well, I think warming the supply tank when doing this is a bit of overkill.

Guess that is one good thing about living up north. I could just put the gun out in the garage for an hour and keep the bottle at indoor room temp.
Lately that has been a 70 degree difference.  ::)

Reminds me... I need to take my bottle to Dick's for a refill.

Anthony, if there is any CO2 still in gun, you won't be able to get a full fill if the gun and tank are at the same temperature. Chill the gun a little in the refrigerator or set the tank in the sun for few minutes.  Just get the gun colder than the tank and you will get a better fill.

I shoot my 115 quite often and am waiting on a 114 I just bought off e-bay.  Hope I don't have to reseal the 114.

Or you could also just do some rapid shots and that will cool the gun.

I refill a small propane tank from a larger one and to get a full fill I poor a cup of boiling water on the big tank which allows it to fill up to the fully filled weight

You can also warm the tank up by standing it in a small bucket with the hot water out of the tap. Filled my 114 right up.  Gun was at room temperature. Won't over heat the tank in the hot water.  Also put the pistol in the refrigerator for a few minutes if need it colder than room temp.
