[QUOTE="Gunpoor, post: 863779, member: 8358"] The only reason I know of for turning/reducing outside neck diameter is to eliminate neck run-out. I don't turn necks and probably never will. As far as how the smithy should throat the barrel, if you are planning to use cup and core bullets, if it were my build, I would have him put it where I could easily get close to the lands. However, if you use mono-metal bullets you need a little free-bore, maybe .050". I always shoot CNC bullets and don't like the bullet seated way off the lands, the reason for me is that it seems harder to find accurate loads. Hope your XP-100 turns out to be shooter! [/QUOTE]
