Now, vary carefully measure the distance from the cartridge base to that line.

Let's say (for example) that it's a .308 Win round, and the base-line distance is 2.235".

For loads with other bullets (and different ogive curves, nose shapes, etc) you first scribe a new unseated bullet with an identical scribe line - jaws again at exactly .300".

Now seat that new bullet so that the base-line distance is again 2.235" and you will achieved the exact same bullet-to-lands distance WITHOUT TESTING.

This works without regard to ogive, nose shape, etc. It automatically seats the bullet where your rifle likes it for best accuracy.

Unless the new bullet is much more pointed, it should also feed through your magazine. That's why I usually do my baseline testing with a plastic-tipped bullet. If that one feeds, every other bullet should feed, too.
