"big" capeash? If your target is power, a bigger chamber is better. As big as you can make it.

1.5"/.75" = 2
22 = 4
24"/4 = 6"
Or bigger

? so the bigger the chamber u have the more powerful, and farther and faster it will shoot?

then, from what I have heard, if you make your chamber bigger, make your barrel longer to get optimum performance from that chamber

Yes, as you increase the volume of your chamber, you need to proportionately increase the volume of your barrel (make it longer) to keep the C:B ratio you had before.

Example:

All numbers are made up on the spot because I'm too lazy to figure out volume of a cylinder. I didn't have math last semester.

Let's say you have a 2500cc chamber and a 1660cc barrel, a simple 1.5:1 C:B ratio. If you increase the volume of your chamber to 3000cc, then your barrel would theoretically need to increase in volume to 2000cc to keep your 1.5:1 ratio.

And one last thing, it's ratio, not ration.
