Re: Help with OAL Gauge Please
I think what you are "feeling" is the resistance of the bullet traveling in the neck of the case.
I use some never dull to "slick-up" the bullet or use a brush inside the neck to make it "slicker". This way the only thing I feel is when the bullet's ogive contacts the lans. You want to do away with as much resistance as possible.
Now, this may mean that your bullet will stay in the chamber, no biggy, just tap it out with a cleaning rod. Just make sure you tighten the lock screw before disengaging the lans.
Take at least half-a-dozen readings with different bullets of the same lot to ensure you are getting a consistant reading.
"One of the ordinary modes, by which tyrants accomplish their purposes without resistance, is, by disarming the people, and making it an offense to keep arms."
