40mm shell questions

[Eeyore]

So I now am the proud owner of a M203. Now what I need are some 40 mike mikes. I don't have a clue whether I should go c02 or propane, or if there is a shell that can do both. What are good brands, and what amount of bb capacity will give me a good spread. And anthing else you think I know please.

Lower BB amounts will have greater range, while higher amounts will of course have greater spread and coverage.

Once you get over 100 or 120 with propane they don't have much range. I can't speak for C02 shells, but you can load those up with any pressure you choose, and they do have more power.

Generally shells are either for propane or C02. You can probably use propane in a C02 shell, but I'm not sure about using C02 in a propane shell. Maybe someone has tried and can speak up.

The propane 180's I've had fired at me were pretty effective, They were the CO2 ones I think but filled with propane, Perhaps that let them take on more propane and have a little more umph then normal?

yes but no. madbull xm204hp, xm108hp have great range on CO2 with an excellent spread/coverage. no compromise on range with 108 or 204 BB's. you will need a CO2 adapter with a gauge though to achieve the proper PSI range for what you're doing.

the xm204hp, xm108hp and xmpb4 are all CO2 and propane compatible. for indoors we tend to switch to propane as it is a lot safer for the ranges you play in. you can still use CO2 but you'll have to significantly back down on the PSI.

CO2 in a propane nade is a no no simply because it makes the valve nearly impossible to release. I had the m922a1's and they can take CO2 with a very low PSI but it was pointless so I ran them on propane only before I sold them.

once you go CO2 and fire off your first nade at 800-900psi, you'll never go back to using a propane only nade! trust me.

typical psi setting we run is anywhere from 450-800psi with the odd 900 psi on a hot day.

great nades on propane... blast 120 bb's at about 70 feet

i prefer using propane nades as they are less powerful so i'm less likely to hurt someone with a accidental close shot and well propane is less expensive...

XM204HP user here, love them, wouldn't switch for anything else. I have a few others like the POM models, they will take CO2 but you'll snap something in your launcher before you get them to fire.

I loaded one up with 1100 psi of pressure at Rawdon to test the theory, they seal and keep the air but you basically need to use a hammer to get the valve to release.

No go.

great thing about the xm's is that you can engage at 50' DIRECT fire. no arching yet. they're great.
