What I do know is there exists steel pipe cutters that look and function like the light weight tubing cutter shown in this thread only bigger and sturdier. They are too expensive to just go an pick one up for yourself but a full service plumber probably has one laying around. Most water lines are now run in plastic but there must be some cases steel is still used.

Find a friendly plumber and pay him what he wants/needs and you could save yourself an afternoon of hacksaw blade and turning work on your barrel. With the cutter the cut would be, for sure, square. Polish in a crown and you are done.
