Advice needed: difficult chambering

[J.G. Terry]

Trim-keep it simple

This post gets more complicated as the OP'er adds more information. As this dance goes on it looks like there is no real answer.

 

[T. O'Heir]

"...on occasion will not..." The key is the "on occasion" part.
Datum points on shoulder are irrelevant except for off-the-lands measurements. Forget the off-the-lands stuff. I suspect you have a case length issue with all your rifles.
In most cases, diameters have nothing to do with chambering issues. Case lengths do though. SAAMI doesn't even acknowledge the PPC. Hodgdon shows the trim-to for the 6mm PPC as 1.510". SAAMI Max case length for the .270 is 2.540" -.020". That's a minimum length of 2.520".
What's your case length?

This is first post about that 6ppc. Back in 2017 he was having problems and I asked if he was turned necks.

I shoot 6ppc and neck is .262.

Interesting , good find , it is puzzling though . I forget names as soon as I hear them , always asking my wife , what's their names ? She just laughs now . For some reason I remember everything on reloading . Be Well ( VN 67-68) Brother .
