1. If a guy got any caliber SA could he get a .473 bolt face replacement bolt and be GTG?
2. From Pacific Tool and Gauge's web site
<span style="font-style: italic">Most Remington Receiver sizes are .700 + .0015 ID. You can open the receiver up to a true .705 ID with the GTR Raceway Reamer and we can grind the OD of the bolt to any size you choose at no additional charge.</span>
What does this mean and what advantage does it represent?
TIA
