Following the guidelines in the safety standard we always point her on this board and spelled out the link above for  2 inch bore you need a piece of steel 6  inches  in diameter.   

Have you given any thought to which  cannon you are going to replicate?  That will determine how long the barrel should be. 2-1/2' will be short.

A 8inch siege howitzer scaled down to 2 inch bore would 15-1/2" long.  6 PDR Model 1841 pattern would be have to 36 inches ling in 2 inch bore.

Get some plans of a cannon design you like and do some scaling before buying steel.

First question to ask yourself is why 2 inch bore and what will you shoot in it?
