I do not recomend using a throating reamer unless you cant get one with SAMME dimensions
and you want something different.
Or have a reamer ground with the throat you want. (one reamer is always better than using
two different reamers to do the job.
I am not saying that a good job cant be done but I feel one reamer is better.(More concentric).
Some smiths buy there reamers with zero throat so they can throat to any dimension the customer
wants and it saves reamer cost. I like to have a reamer ground for the chamber desired. this way
it can be used again on the same barrel to clean up the throat and the chamber after hard use with
little change in the loads that were used before.
I have had to throat chambers that had zero throat because of pressure problems and I
prefer to use a chamber reamer to throat and clean up the chamber at the same time.
set the shoulder back, and head space for a good job.
This is just my preference.
