You can tell how awesome a cannon is by the pressure used.

Look in a steel fitting....

He never says it is cast it might just be brass pipe cut and threaded.

It IS cast. Read the title, read the OP, read several posts in the thread. It's cast red brass.

Yes they will be rough inside. You could take a 1" drill bit, lock the pipe in a pipe vise (not a regular vise; pipe vises have V shaped jaws) and bore it out.

Stupid quote of the now:
joestue "The chamber is rated to 100 psi, it don't say that on the side, but the 2 inch stuff is rated to 300, so by analogy..."
"only the last two feet hear the end is black cellular core"
"I'm taking it to 300 psi"
