Given all the indubitable skills and talent on this forum; any ideas on how one would achieve that rifling??>>

Homemade broach very similar to a spline broach would be a possibility. I think taking it out with a single cutter for each groove would see the cut wandering off over such a length.

Is the rifling straight or has he imparted a slight twist in it?

A spline broach used on a rifling bench would be the likely method. The rifling bench is a long table with workholding features at one end and a helical cam (helix geometry matching the rifling twist) to mount and guide the broach at the other.

There will be a twist in the rifling – the purpose of the rifling is to get the projectile to spin during flight, which stabilises it.

I'm not any sort of gun expert – the above is the sum of my expertise on rifling.
