C360 turns nice with flat on top HSS on the 7x in my experience. Really sharp with a tiny nose radius worked great for me. I turned almost 50 feet of 3/8" into little 1/2" long orifices and never found anything that cut as well as flat HSS. It did not like carbide or any top rake on the steel in my experience. I spun it around 8 to 900 rpm and fed .002" per rev and got a really nice surface finish.?

I made a 5in brass cannon from 1.25" C360 brass on a big Southbend lathe at my local Markerspace and plan to try it again on my LMS 7x16. What tooling and speeds are recommended?
