Hello Randall,
I am just about to place an order to PTG for a 300 whisper reamer.
I had a look at different dimensions sources for that reamer and the one published in PTG reamer's specs seems quite wide (maybe for AR or semi-auto type of chamber?).
The dimensions specs in Ken Howells book about chambering reamers are a bit tighter.
I played a bit with redding reloading dies in 30/221, and made some whisper cases out of 223 cases. after mesuring them, it seems that they are even tighter than Ken Howells specs.
I am wondering wich way to go and what dimension to provide to PTG?
I will be using the whisper in bolt action rifles only.
Nicolas
