Depends on many things. Will this be using propane metering? What king of ammo, weight, friction in the barrel? Length of the chamber and barrel, the ratio dosn't tell us the length.

How about you get us a link?

I have a feeling he's asking about a pneumatic launcher.

Usually somewhere around 80-100 yards or so. The 1.5:1 should be a bit farther like over 100 yards.

A 1:1 ratio is a barell and combustion chamber at same length right? All that stuff will help a little bit. But it defintly depends on the ammo and air:propelent ratio

No bagntag, a 1:1 ratio is the barrel and chamber having the same volume.
