6.5 4s neck clearance

[mpwolf]

Just curiouos how much neck clearance you prefer when making 6.5 4s brass for hunting rigs? I built a rig using a PTG .081 FB/.296 neck reamer. Turns out the reamer is a touch undersized, so my fired necks are 0.294". I hadn't realized this when I prepped brass, and my loaded rounds mic .293". I know I need more clearance, but I’m curious how much is a good idea?

.005” is a good idea

I'm running Starline brass and have a loaded round of .2915 that would give you .0045 clearance compared to you neck reamer of .296 which should give you enough. It would only give you .0025 from your fired brass which might work fine. Not fun changing brass but it might be a reasonable option to pickup a little space. Otherwise you are turning necks.

What Starline brass are you running? I use their brass for .223Rem and .308Win, but don't see a SAUM case listed on their site?

I'm turning neck already. I just hadn't turned them enough. No big deal to take a second cut, but I'm just curious how far is enough. I would think 0.005 clearance would be about right.
