Coaxial .45
Coaxial .45
I am considering a coaxial build with a .513 bore. How much smaller should the inner tube be compared to the outer or how much space do you want between them? I would guess as much as possible, but I would rather have a experienced opinion.

Not enough detail to offer advice.
What is your planned length, width, design considered, firearm, etc?

I thought about 1.5" x .058 for outer tube and 1.375 x .035 for the inner 4130 CM. As many 50 or 60 degree cones as I can fit. Aluminum outer tube would be nice to drop some weight but I dont know how much difference it would make.
