from what I've been reading, its no big deal to put a bulk fill end cap on a qb78, fill from a paint ball tank, disconnect, and go. Could you also leave the tank hooked up while you are shooting? or would that require some sort of extra hardware or plumbing that I'm not thinking of?
It would be great to have the tank on a remote line for bench or prone position shooting, and the bulk fill for carrying
-
You can leave it hooked up for shooting.

IF you aren't moving around and shooting from one spot, hooking up to a remote line works great. Not like an air tank, there is no worry of over pressure by staying hooked up (and if you wanted to, could hook directly to a 20 pound bulk tank).
Cobbled together a little rest from scrap wood and the foam neck pads used on EMT spine boards, just the sight size to hold a 20oz. and remote under the rifle. Most of the pellet testing, trigger adjustments, etc were done set up like this.

and if you put the bottle upside down you could just fill the tube then disconnect the hose and use the gun that way too , right?

Almost.
With a regular remote (can find them on-line from $19-$29), once you turn the fill tank to off, there is still co2 in the remote line. Can't pop the quick detach off (its under pressure..and if you do, will shoot the little o-ring in the QD fitting to the next county). Could unscrew the co2 tank from the remote line, which would vent the co2 in the line (but the gun would stay full).
Some remotes have a slide check...which is a sliding type of vent valve. With those, can turn the co2 tank off, slide that slide check and vent the line, and then just detach the remote line from the rifle (which stays full). These remotes cost $33-$40.

darn, next county over in two directions are two different states. I don't want to go out of state looking for my o-ring :P
seriously though, thanks Ribbon, so the shoppping list will be a remote with slide check, co2 bottle, and bulk fill end cap :]
-
Well...live in Louisiana, so its a long way until I hit a county ( Parishes here).
To be honest, found most of the slide checks leaked after a short time...not a big hissing leak, but a slow leak. So be sure to turn the on/off to "off" after venting...or it will sit there and slowly vent your paintball tank while you are shooting.

if you thought you were gonna be shooting a lot. you could carry the tank on your hip/leg. probably not necessary in hunting situation but possible. personally i think the greater the volume it seems the better the co2 will shoot. ;D more room to turn to gas. i guess. ;D
-
Agree with aack73, larger volumes of gas are more temperature stable. Co2 tends to self-cool; converting from liquid co2 to gas cools the liquid co2, so having more liquid helps evens out that per-shot cooling.
