Ok
What I need to know:
If i have a load with .327 bullets and in a mistake
Load them in my smallest Mauser .3225
What could happen?
I always full size my 8x57 not having trouble with
Any of my Mausers.
Yes I could neck size and mark this to avoid any risk

Or I could fit a barrel on the rifle who not have
This “problem”

The rifle is bought as a shooter and not a collectible item.
And I still have a original barrel for it.
