Good but i've had issues - Forster Ultra Micrometer Seater Die

I've had the die for a couple weeks. I've done a bunch of research and this Forster looks like the real deal. I love the sleeve for concentricity and the micrometer is super helpful when fine tuning seating depth. The only thing I'm unhappy about is it leaves a fine indentation around the bullet at the ogive, enough that's about to be felt w a fingernail. I have read u can take the seating stem and send it to forster w a bullet and they will cast the stem around the bullet. This could be user error but I've followed instructions and can't seem to figure it out. I'll admit they shot wonderfully even w the dents...just not a pretty made round.
