I thought everyone used the scrap piece off the front of the barrel to make gauges with.
No need for the viewing port.
It just makes the gauge inconsistent.
You need the bullet touching the throat more than 180 degrees to acurately determine seating depth.</div></div>
Can you explain why more than 180degrees is needed to determine seating depth? It is because your looking to jam it in the rifling and you need full chamber support to do it? </div></div>
that is exactly why. if you have 180* or more of opening, you will most likely get a false sense of when the bullet makes contact with the lands. with the bullet not being supported in the throat, it will have a tendency to ramp/deflect toward the opening as it makes contact with the lands and continue to push out until something bottoms out such as the case neck (which is far looser in the chamber than the bullet is in the throat). with full diameter support, when it makes contact, it makes contact and stops.
