Daryl, Thanks for your reply. I thought when I checked it that the 14" twist was odd. I haven't slugged the barrel yet, but I did measure it several times with a couple of different small hole gauges and a tenth mic. The lands are narrow enough that my small hole gauges will work between them. I'm getting .3074" - .3075" groove dia. The bore measures .2994" - .2995". The only markings on this barrel is a large Z stamped on the breech face. It doesn't look like a CZ stamp, it is plainly just a Z. So I am assuming it may be an inspecters mark. A fellow I talked to last nite after I posted here suggested that it might shoot the Sierra 155gr boattail Palma Match bullets really well. I don't know. I was going to use this barrel on a Mauser tactical/target rifle build that I am doing, but I'm not sure now what I want to do as I have other barrel options. I still think this is the smoothest barrel I've ever looked thru though. Thanks Again.
