Which reamer for 6 dasher with 105 Bergers

[Kyskeet]

Building my first 6 Dasher, intend to shoot fire formed Lapua brass, and 105 Bergers. I will be buying my own reamer for this and subsequent barrels. Is there a preferred reamer for my brass/bullet combo.

A .272 neck and a .130" freebore will be perfect for not neck turning the brass and seating the bullet to just the right depth in the neck while being .020" off the lands.
