Bushing for .334 chamber?

[.334 NK]

Hey Im a little new to the tight neck game and I know this question has probably been asked a million times before. I have heard alot of stories on what bushing you should use according to chamber dimetion. I was wondering if some of you could help me solve the issue. I shoot a .308 with a .334 neck some have said .002 under that and others have said .001 or 2 under loaded round? I know I need the small neck clearence but how do you know what bushing to use to get that clearence with the tension?

A good starting point: turn the case necks for a total clearance of 0.002" ( 0.332" loaded round diameter) and use a 0..328" diameter bushing - you probably won't need another bushing. Good shootin'! RG
