Does a seater die contract the bullet tip or somewhere on the ogive? I'm trying to figure out why I have slight variations in seating depth when using the same brass and bullets.

I wonder if this is what is happening. I'm using rcbs dies. Loading 223 hornady bthp, 68 gr.When I used to load for rifle, I had seating depth inconsistencies that affected accuracy. I found that the seater stem wasn’t drilled deep enough. The really pointy bullets and/or the polymer tipped bullets were too long and the seater stem would index on the tip of the bullet rather than the ogive of the bullet.
You can actually send Hornady your seater stem and a sample bullet and they will drill it out so that the stem doesn’t index on the tip of the bullet. So this all leads me to believe that you want the stem to index on the ogive for best accuracy. At least for pointy and tipped rifle bullets.
Put some magic marker on the tip right before it gets seated. Then look at the seater stem to see if the tip of the bullet marked itI wonder if this is what is happening. I'm using rcbs dies. Loading 223 hornady bthp, 68 gr.
This^^, or look at the bullet to see where the ink is scratched by the seater stem.Put some magic marker on the tip right before it gets seated. Then look at the seater stem to see if the tip of the bullet marked it
