Co2 Bulkfill

[Hsing-ee]

I didn't follow the freezer advice because I was a bit concerned about condensation and rust, but if you make sure you oily rag the pistol it should be OK. Ice-cream is top stuff, I like the Carte d'Or stuff, especially the Rum and Raisin - do your local smugglers/pirates eat this? And of course the tubs are excellent for all kinds of DIY storage and paint mixing purposes....

The Brno B-96 is one of the best airguns ever! You must try machining up a 10, 12 or 20 shot mag, it will be like a miniature Hotchkiss machinegun.

Confession time! It's Black cherry flavour frozen yoghurt! I've never been quite the same since I started using .177, I fear a pair of Espadrilles looming on the horizon for the summer.

My empty pot is full of frozen chillies from last years crop, this never ceases to annoy my wife who grabs it with a look of hope every single time.

You cán overfill CO2. Its filled by weight though so simply check max filled weight. Its mentioned on the cilinder. If its a non-detachable cilinder, it may be in the manual. But in case of a grip reservoir, it wont take much more CO2 than the 12gr bulb gives it. If overfilled, you will hear it during first shots. You can also bleed it on some guns.
Yes if yr bulkcilinder doesnt have a syphontube, it needs to be inverted to fill.
Imo, bulkfill with a gun with non-detachable cilinder is pretty much worthless.
Even if you dó dryfire shots, to get a max fill is terrible. Its just not as good as freezing a cilinder.
If you cán just use 12gr bulbs (or if you have detachable cilinder, use a freezer)

DONT put the whole pistol in the freezer!! If you do nót have detachable cilinder, use bulbs.

A CO2 fire extinguisher has a dip tube so can be used upright. Convenient in 2kg size (net weight) and works well for removable cylinders...200 to 250 shot count per fill.

I imagine it would be a bit of a faff on an internal cylinder ever 70 shots or so.

Fill instructions normally state not to exceed total weight. Seems the issue may be related to elevated temperatures and expansion of contents!

My co2 rifle has a detachable cylinder and to get a maximum fill I put the cylinder in the freezer for 30 minutes and fill from a fire extinguisher. I keep the extinguisher in the airing cupboard so it is warm. It is easy to overfill so check what the correct maximum weight is and release some co2 to the correct weight.

That's not a bad idea. I have never managed to fully fill a detachable cylinder, even when it is chilled in the freezer, and the bulk tank (Fire Ext) is at room temperature. A slightly warmer tank should sort that out. Not too warm though, the bulk tank has temperature limits.

Than you probably didnt have the cilinder in the freezer long enough.
I had ny bulkfill cilinder in the garage, at outside temperature. Never had a problem with max fills
