On my seater die the hole was so small that it was hard to seat to the same ogive depth. What I did was make a new on that has the hole opened up to .221. That way hopefully I am seating according to the ogive or at least that is my thinking. I tried some test runs this morning and it seems like it is going to work a lot more consistently than the original setup. The .221 is closer to the bullet diameter than .214, the diameter of the Hornady comparator, so it would stand to reason it would be a more accurate measurement.

A few test ones I did are staying within .001" and that is with the Hornady that measures at .214 on the ogive and not at .221. I suspect that they are all at the same oal length when measured at .221 of the ogive. It seems to be seating them all to the same ogive depth so now I just need to sort by bearing surface length, using teh method in the pictures above.

Hope what I said makes sense, if not please ask and I'll try to explain my thinking (which might be flawed).
