    I think I'm going to be ok. But a quick question. I never used the crimping die. My bullets are snug in, but using a bullet puller I'm about to extract them with 2-3 taps at the most. When I was trying to pull bullets out of factory ammo, it usually took 20-30 pounds.

    Do you think I'm ok?

  2. I would put the crimp die in your press, insert a cartridge into the shell holder and run it up all the way then adjust the die down to where it just touches the brass. Back the cartridge down so you can adjust the die and crank the die in about 1/8 turn. Run the cartridge back up into the die and check to see if it gave the neck any crimp. If not or if not enough give it another 1/8 of a turn. That'd be 1/4 turn total and that should be plenty. Just go slow so you won't over crimp things. Other then that looks like you've got things pretty much figured out. Congrats and welcome to the wonderful world of reloading and saving money.:D

    Than you, because of you guys helping everyone with all your knowledge I was able to get all the info I needed to start, an successfully reload my .40 Ammo today for the first time an was great at the range groups at about 1.5" to 3". Thanks for all the info you put out here for us.

    @Bocadan: just a cautionary note: too little crimp results in ammo whose bullets can reseat when loose or even in the magazine,resulting in overlength rounds (magazine jams, failure to feed, failure to return to battery or firing out of battery) while underlength rounds will cause overpressure inside the chamber when firing.

    BUT by and large, less crimp is better than too much crimp, as this can result in a catastrophic chamber detonation.

    If you are doing a taper crimp, simply measure the crimp (outside case diameter at the crimp) of factory ammo and adjust your crimping dieto the exact diameter. With roll crimps, it is a little trickier.

    A good rule of thumb (yeah, been doing this so long, the TLAR method works for me...."That Looks About Right" ;) ) and all i do is visually inspect the first couple of finished rounds. Before seating, the case mouth is chamfered and deburred, and when done loading, the edge of the case mouth should not appear totally straight but have a slight cant inwards to the bullet....it is not digging into the bullet (due to the material removed in chamfering and deburring) but instead uses the interior diameter to grip the bullet firmly. Confusing, I know. Maybe TN can describe this better, I know he knows what I am talking about.

    In a nutshell: too little crimp will give you headaches maybe, but too much crimp can blow up the gun.

    Go slow with calibrating your gear, and you will enjoy many years (and save many dollars!!!) with your new hobby!

    Enjoy and shoot safe!

    Hmmm.....just a question here....how do you clean your cases?

    Those finished ones before I got a decent cleaner and used detergent + a 3 minute cycle... I've since pulled the bullets/primers etc out and re-cleaned them. Shiny as ever now but thank you for noticing...
