[QUOTE="greggc1960, post: 887578, member: 67952"] Ok, thanks, that gives me something to chew on. Its fresh from the smith, new barrel and bolt head, so I dont have any previously shot brass. However, I believe that negative headspace thing is in play here. The eight spent cases from yesterday chamber very easily, but the live rounds dont. Takes a bit of work to close the bolt. Last night, I noticed a couple of burrs on the back of the lugs, I could hang my finger nail on them, so I disassembled the bolt head, and carefully filed the burrs off. I figured it couldn't hurt, as long as I did not change the lug length or engagement area. Its a little smoother, but still hard to close on a live round. Think I'll pull a bullet to get an empty, and start fiddling with the shell holder, try and bump the shoulder down. Sidecar Flip, would you explain shoulder datum for me, please? I'm dont know what that means. Thanks to everyone for their time. Gregg PS Do Savages benefit from bolt lapping? If my chamber is real short, would carefully lapping the lugs help? Gregg [/QUOTE]
