As background, I made my first 7mm Weatherby loads here:

Per the first thread I ordered the micrometer seater for my Redding die and went today to use it. As background, to achieve the original OAL (same as a factory 160gr AccuBond) I had to screw the bullet seater almost completely into the die. The tightening ring for the seater even had a bit of exposed thread on the inside it was so low. This was after the usual die setup per instructions of running the seater die down on a case until it just touches the shellholder and then backing the die off 1 turn and tightening the adjustment ring for the die.
Today I swapped out the old seater for the new micrometer seater. I adjusted it to zero and installed it, then installed a practice bullet into some brass. The length was about 0.03 in too long so I screwed it in one turn past the zero. It was still too long so I went the last extra 1/4 turn until the micrometer adjuster on the seater was screwed in as absolutely far as it would go.
As you can see by the photos below the practice bullets are not being inserted into the cases as far as they used to be.
To fix this do I adjust the whole seating die down a bit?
Use the old seater insert until I finish load development then go longer?
Forget about the approximately 0.02 inch difference I now have and ignore it?
Suggestions welcome.
Ironically they're both now the same length, even if it doesn't look like it. So apparently the seater die may help with consistency but not at my original length...
And ignore the marks from the seater die near the tip of the bullet. Those are from me checking out how well they fit and if the tips were hitting.
