Adding to what Foxx suggests, I always start a new load/bullet development by taking a properly sized brass and seating the bullet to what my LNL gage says just touches the lands. I chamber this dummy round and verify touch. Once I have this set up, I mark the brass with bullet, gun, date info and keep it as a "standard" in a special loading block assigned to that gun. As the throat erodes over time, this dimension will of course increase.

That way when I want to load that particular bullet again, I set the "standard" in the press and adjust the seating die to just touch the bullet. Makes the set up go much quicker.

And this is just a suggestion that will help others to help you in your quest. Please use periods and capital letters in your writing. Would make reading and understanding your sentences much easier.
