Hornady's micrometer adjuster screw works with any of their new dimension series dies, creating a "competition" style seater die for any caliber they offer dies for.
I got started in reloading by straightening the bullets in a bunch of S&B 7.62x25 ammo I bought. I have a CZ52 with an off center chamber/bore that will jam the bullet into the lead if it is not seated straight, and rotated to just the wrong orientation when chambered. (I got a couple of blown primers that way, but no damage. The bolt face left it's impression on the rear of the brass too.) Anyway, I started with using lee seating dies in a lee hand press. They did not straighten the crooked bullets very well at all (the seater plug had a lot of side-side play). Then I tried an rcbs set (30 mauser, but close enough), and it worked better, but still not consistently. Finally, I bought a hornady 30 lugar seater die (upper dimensions are almost identical between them), and it works perfectly every time.
YMMV, HTH, etc. ...
