Measuring cartridge OAL: how hard do you jam?

When measuring OAL using a Stoney Point gauge or similar method, how hard do you push the bullet to the lands? I've been pushing it until I feel the bullet lightly touch, but I'm getting a pretty wide variance in measurements and wonder if that's because I'm not doing it right.

In speaking with others, some are telling me that they really jam it hard.

If you jam it hard, what setback do you use? (223Rem and 30-06)

Try different amounts of force until you get a consistent reading. that's the best advice I can give. That's all I do.

I use about 3-5 pounds pressure to keep the cartridge/guage seated until I can get the lock screw tight. Be careful not to wiggle the rod too much or it will break off at the bottom of the threads.
