Re: Standard or tight neck ?
True to a point. Evening up neck thickness will help to keep RO from becoming an issue, thus less accuracy. Combined with a tighter neck chamber, brass life in the neck area will be MUCH better, and this will also help keep neck thickness the same over time from less stretching.
.002" total neck clearance, .003" at most, is all you need, any more than this is less than desirable, unless hunting dangerous game with the rifle. It simple over works the brass, so does bumping the shoulder back more than a thou or so... Both should be kept to an absolute minimum unless it's a DGR. Zero headspace will center up the bullet with the bore better than a tight neck, as the neck isn't laying on the bottom of the chamber and is tight to the shoulder, which centers it perfectly, zero runout is assumed.
