Re: Is this a properly deburred flash hole?
This is a case of "Less is more".
Some flash holes will have a fingernail on one side and this affects the flame front.
It needs to be removed only to the surface of the case web (Flush). more is not nessary
and may weaken the web.
To much chamfer will also effect the flame front(Burn)of the powder by dispersing it, so I would
back off a little.
