I have used the uni throat reamer on my .223 that the throat was to short for 90 gr. SMK. I rented it from 4D reamer for like $40. Just be very careful you don't take to much as it cuts really fast and easy. I used several dummy rounds with the bullet set way long to use for measuring my cuts. I also used the Hornaday tool but the dummy rounds were more consistent.Is there a reamer, that will allow you to to seat a bullet just outside of where the donut forms say for 70-85 gr bullets?
will the longer throat and free bore tolerate the 55 gr varmit bullets?
has anyone used a uni throat reamer to set the free bore?
