For example , i have a 100mm chamber right but the closet selection i can choose is sch40 4'' but in australia we use the metric system so its kinda hard to get accurate measurements, Visit The blunk lake site click on ratcal live ( which is a C:B ratio calculator). you will see what i mean .
:roll: .

BTW has anyone built a coke can spug gun .

Do you mean Burnt Latke?

Just measure the volume of your chamber and the volume of your barrel, it matters not what measure system you use as long as you use the same one on chamber and barrel. Just do the math Chamber V/Barrel V.

Yes on the Coke can spud gun question. Work on your spelling please. There is a spellcheck button there....use it.

Measure everything and convert it to inches and go from there.
