I can attest that the Rem Hammer Forged barrels are smooth. I had a 5-R Milspec that was one of the best shooting, out of the box, factory rifles I've ever owned. Cleaning was a dream. The bore looked like itty bitty people crawled through with polishing equipment and made every square milimeter as shiny as possible. I replaced that barrel with a Benchmark 5-C after over 10,000 rounds.

The trigger on the 5-R Milspec stunk but with a replacement Timney the rifle shot great in the factory stock.

One thing certain, CHF barrels are not only smooth (if the mandrel they're formed on is) they are also durable. The process was developed to provide barrels for the MG-42 which, at it's high cyclic rate of fire, absolutely ate barrels made by traditional methods. The process is expensive due to the cost of the equipment so you'll find most aftermarket barrel makers sticking to the old "button" or "single point cut" methods of rifling.
