This is a Xr-100 that we rebarreled (sorry for the poor pic). We squared the action and bolt, lapped the lugs, surface ground the recoil lug, glassbedded the action and installed a 1/8 twist Benchmark barrel and finished it at 28 1/2". Caliber is 6 BR. The customer brought the target by the shop that he shoot at 100 yds, the group is 5 shoots and measuring from outside to outside and subtracting the bullet dia. it measured .015. Very fine shooting on our customers part..
