I got two new Kriegers chambered up yesterday and I have to say that I have never been so impressed. After dialing in on the bore, a real fast spin of the old lathe showed how straight these barrels were bored. The first one (a 6mm 4 groove 13.5" twist) had one section about 4" long out towards the end that ran out just enough for the eye to register a wiggle. After that section was cut off, it ran dead nuts straight. A dial on the back end of the 8"indicator rod showed less than .0002 runout. I thought I got lucky once, but it turned out to be twice! I threw the second barrel in the lathe (a 6mm 4 groove 8" twist) and once it was rough centered before boring, I about hit the floor when I looked down the bore while it spun. No movement. None. Straighter than an arrow. ANd that was before it was totally dialed in even. Amazing. When I ran the mic on the back of the indicator rod on this barrel, it basically flatlined. Less than .0001 runout! If these two barrels shoot as good as they were made, I'm going to have some serious fun. ANd so far, so good. The 8" twist broke in easier than any barrel I've ever done and I've done more than I care to remember. After checking to make sure my Coppermelt hadn't died with a check of Eliminator, I could see the Coppermelt was fine. The barrel just wasn't copperfouling! No blue patches in the entire break-in process!! ANd I was using bullets with very long bearing surfaces too. Unbelievable. TO clean it is a joy. Krieger, your doing great. Keep on doing what you're doing!
