Back many years ago i bought a 4 die set of lee 9mm reloading dies. Just now got around to using them, and i can see that they were made for a progressive press. I have loaded 38 spec for years and the third die seated bullet and crimped the bullet at the same time. I can accomplish this with the 4 dies set but it will take two more trips for all 600 of them through the press, if i had the 3 die set it would only be one more trip. So i was thinking, is my 38/357 seater/crimp die close enough in size to seat and crimp the 9mm bullets in the 9mm cases?
