Bullet distance from the lands.

Go to Youtube and query "bullet seating depth." Seating bullets for hunting is usually just off the lands. For bench shooters, it is either off the lands or jammed into the lands from 10 to 20 thousands. (0.010 to 0.020). Good luck!
It has more to do with the ogive than the manufacturer, secant ogive bullets are more prone to to hit the lands and grooves slightly crooked where tangent ogive is much more forgiving due to the shorter radius curve. It sounds like a hybrid gives shooters the best of both worlds.

Get a Hornady OAL (overall length gauge) and a dummy case for your cal.
Easy to use and accurate!
You remove the bolt, stick your bullet into the dummy case which threads onto the gauge, put it in your chamber, push the bullet forward until it touches the lands, pull it all out and measure.
Subtract 20 thou and there you go.

very interesting video. i wonder if the tool he used is as accurate as the hornady OAL guage.

I like the Hornady OAL gauge.
I took a 6ppc case that I fired from my rifle and had a machinist friend thread it so it goes on the gauge.
Easy as 1,2,3 to use.
Keep it simple,use your neck sizer carefully so the bullit justs slides in with a little resistance.measure the oal of a factory round.add .100 to oal,chamber round, carefully extract.measure oal,if the round is shorter than the plus .100,you now have the distance to the lands.note each manufacturer has a different nose profie,so to be safe repeat for different types.To be accurate,take a diameter measurment of where the lands mark your bullit.the special tool you refer to is a piece of tubing with that diameter squared on a lathe ,about 1 inch long.put tube on finished round ,now you have a way to measure oal to olgive with your DIGITAL vernier.I hope that helps
