Slugged the barrel and it was .355 on the grooves and .349 on the lands. Measured 10 bullets and all were .355 on the money. Not sure what that tells me except that the lands are .003 in height. Weighed a bunch and compared the extreme spread to some MBC cast bullets and the Hornady XTP's. Hornady was #1 with a ES of .2 and a SD of .1, the MBC's came out with a ES of .9 and a SD of .67, the Penns had a ES of 1.5 and a SD of .47
