Nice! Did you come up with a plan for cutting the center bore and lugs out of the action? I'd go bananas in my shop scratch-building Remmys if I could figure that one operation out. Broaching is the best I can come up with without major EDM capability.
Your press is admirable. I like the splined turret and the offset ram. Next time I decide I need another press, building my own will be the way to do it.
Study Robert ChambardI'd make a mandrel with a milled keyway, to fit into the bore and probably grind a broach from HSS, to fit the shape of the raceway.
I've also considered a shaper, with some custom made tooling,
or even making an oversized adjustable cut rifling head. I think it would cut some nice raceways. Adjust the depth about .005" per pass. It would take awhile, but supposedly they work well.

Love my Benchmark barrel on my F-Class rifle. Didn't know that the rifling machine was built right here in our area.I have a neighbor/friend named Cliff Labounty who's well known for his barrels and rifling machines. I made one of the parts that are on the CNC cut rifllers he made for Benchmark and Kreiger.
I've talked this idea over with him, and got some good pointers on designing a head based on his rifling heads. I'll check out Robert Chambard and see what I can learn.
