How Vital/Dangerous is out of spec COL

[Xerox]

I ignore the COL and seat according to the bullet I'm using and the length of the throat.

That's my practice too.

I measured each of my 416's and 50's and was surprised at the difference in OAL between them. Major pissoff having to do 3 different seating depths in 50 and 2 in 416 but it is what it is...

Ever given Meplat trimming/uniforming a go?
