    I have a guy who is an engineer at a barrel manufacturer who is telling me that he gets a 3.730 coal with a sammi spec reamer and throat. 28 nosler, 195 eols .010 out. new gun

    From what I understand...he would have to be about .120 into the lands to get that kind of coal....am I missing something??

    That does seem long, iirc my xbolt is right around 3.64 max with the 195.
