Thats the plan. I had no worries about it just was not expecting to have dummy rounds made. Thought it was just going to be reamed off of gauges and then i would find the seating depth. This is a rented reamer not cut to my specs on what i wanted for freeboreIf it has zero freebore, why not seat the bullet a little deeper in the case. As the throat eventually erodes, you could then seat the bullet a little further out.
