i think my original topic is out on date now so i make a new one.

i think i am going to ask larda make the endcap on the back really long so the chamber gets 27.6" long and 3.5" in diameter.

what do you think of DDT in that chamber at 10x?

EVBEC says : 1645fps :D (46gram golfball)

I'd say your fine, you'd need at least a few metres IMO.

Unless you have several metres of unburned fuel between ignition points, you needn't worry. DDT runup isn't a whole lot shorter at 10x than it is at 1x.

Congratulations on the volume increase spudfarm. What kind of air source are you planning on? Because that chamber at 10x will require more than 1 cubic foot of air per shot. Or is this going to be a non-portable backyard thing?
