That article in Precision Shooting about hammer forged barrels has a part two where they did some accuracy testing. They took some Ruger factory hammer forged barrels and set them up for an AR. They shot under a minute consistently with several types of ammo and some groups were in the half minute range. Not bad for $60 barrel blanks.

IIRC hammer forging is the way they do polygonal rifling. Supposedly slightly more accurate and higher velocities, but that's just what "they" say.
Yeah the blank is only $60, but the machine is $20 million. You have to make A LOT of barrels to make that one come out.

Wow, I thought that was a great article. I knew the basic principle of pounding the blank around a mandrel but never knew what really went into it. Thanks!
