Re: Neck turn ??
" This Norma brass and my loaded necks are.293-.294 and fired ones are .294-.295."
First thing to understand is the fired cases have expanded to the chamber wall and sprung back at least a thou. Meaning you have more clearance than it seems when measuring your loaded and fired cases. It's obvious that you do have a tight but safe chamber. Many accuracy buffs pay a lot of bucks to obtain that, others would kill to have yours.
That said, it's also clear that if you get sloppy careless with your cases and loads you could easily get a pinched bullet and damage your rifle.
That said, I like to use neck turning tools for my more sloppy factory chambers and conventional brass just to even things up a bit, so....why not you?
