The issue being that a normal reamer would 'guide' itself based on the reamer being able to fit tight throughout the entire chamber (throat, neck, body), whereas one that cuts only the throat would only be touching in the throat, and therefore any small offset of the other end of the reamer would cause the throat to be cut not concentric to the bore and existing chamber. Hope that makes sense.
So you think that this method could not be done if the reamer was built to the standard Grendel reamer specs yet only had a cutting surface infront of the shoulder? Nothing would change with the reamer except for the cutting surface.
I was thinking the reamer would naturally center as it follows the path of the chamber and come to a deadstop on the shoulder when the cutting is complete.
Thanks for your insight.
