.338 chamber neck clearance

[Texar2]

About to start chambering my new build and had a question regarding neck clearance. The reamer I have is a JGS 338 RUM Saami With a neck that measures .372. Loaded rounds are measuring .365 in the neck area. Also the body is measuring about .006 clearance for full length sized brass. I feel like I might need a tighter chamber than this. What are you thoughts? Any comments are appreciated. Thanks.

That seems a little loose for a precision rig. I would go 0.003 - 0.004" on the neck. You could always have a custom sizer made to deal with the body clearance.
