Before you spend the cash on those expensive dies, you might try what I do. I barely start the bullet as straight as I can. Then I rotate the case 180dgrs and seat it another 1/16". Then 90dgrs, then 180dgrs, and keep repeating until the bullet is seated. I've had my BIL check them on his gauge, and they come out the same as the ones he seats in his inline dies. It is a slow process, but I am a low volume reloader, so I don't mind. :))
