[QUOTE="Edd, post: 1334770, member: 30592"] The lead/freebore shown on that reamer print isn't .165", it is .148". The .165" length is the freebore plus the transition angle. The throat measurement isn't .148", it is .257". But the throat length shown isn't the actual length. It is a 1.5° angle calculated to a bore diameter of .325". The actual bore diameter is .330". The 3.277" length shown isn't the COAL, it is the length from the bolt face to that same point of a 3.25" bore diameter. Your bullet nose extends well beyond that point. [/QUOTE]
