    find I'm like a lost puppy when it comes to bullet seating and crimping

    we need to start an "adopt a reloader" program

    We already "have" one. There was a thread posted where those of using willing to help (mentor) live, and new reloaders could see if anyone lived close to them.

    But your issues seem fairly simple, what do you need to know?

    Seating simply "pushes" the bullet into the flared case to your desired OAL. Crimping removes the flair so the bullet doesn't then move around.

    Seating: You need a set of calipers (VERY IMPORTANT) to measure your OAL, you then adjust the seating die (turn to the right to shorten OAL, left to lengthen) and measure/repeat until it's correct.

    You can also measure the crimp to see if it's correct. I don't reload that caliber, and aren't sure what the "rules" are for crimping it... but with 9mm, the correct crimp is something like .377?

    Here's the first of a 5-part SERIES of videos, on reloading with the Dillon 550B. He shows setting up the press, each die, and discusses the how/why. Even if you're not using a Dillon, die adjustment is going to be the same regardless of the press (ie, locking ring is the same, turn die right or left does the same thing).

    There may be some similar videos for YOUR press on youtube.

    In addition to what Ron has said...all good advice in my opinon. A few fact would be helpful.

    Press set up? Bullet and powder used?

    Really, what is the issue? It sounds like you may be struggling w/ OAL & how much to crimp? OAL, easy, use the data that matches your bullet or load to the longest OAL that functions in your pistol. Crimp, most struggle w/ too much or too little. If you removed the flare from the case of a semiauto round, that is usally enough. SOme will measure w/ calipers, fine, but you can see if it's too much or not enough. CHeck by dropping dummy rounds into your pistols bbl.
    If it's a roll crimp for a revolver, even easier. You seat to the crimp groove, that sets you OAL. You crimp until there is a perceptable roll into the crimp groove or cannelure. You should have a crimp groove to apply a roll crimp for best results. If you bulge the case, that is too much crimp. If you can not see the case mouth roll into the groove, it's not enough.
