[QUOTE="Buttermilk, post: 1408489, member: 5262"] My factory Remington barrel had ~0.500" of freebore. It would shoot certain loads at just under 1 MOA. I replaced that factory barrel with a Krieger 5R, cut with a chamber that has 0.098" freebore and a 0.343" neck diameter. Now, the gun shoots 0.4 MOA with only about 40 rounds down the tube. I also have a Wyatt's extended box that allows 2.825" OAL. With the 0.098" freebore, I'll have ~ 0.075" to chase the lands and keep it inside the box. [/QUOTE]
