    I'm just getting into reloading and looking at buying my first sets of dies for 40 S&W, 45 ACP and 9mm. I fire all from automatics (Springfield, Glock, Beretta) respectively. Do I need a crimp die? As I look at sets some have them and some don't. I saw in another post that "some seating dies for pistol calibers taper crimp when you seat them" so when I load these calibers will the taper crimp be enough with a seat die that taper crimps? Or do I need to have a specific crimp die? Not clear on this - please someone educate me, I'm sorry I sound like such a rock ape here but I really want to grasp all the details before I screw this up. Thanks for the help.

    You need to be able to crimp. Well, actually, for auto loaders it's not much of a "crimp", it's more like taking the expanded flare out of the case mouth so the cartridge will chamber easily. Meaning, you need to take it easy even with a taper crimper.

    All handgun die sets I know of include a crimping ring in the seating die so, no you don't NEED a seperate crimper die. MAYBE later on, after you get well grounded in the loading process you MAY want a seperate crimp die but, if you do, you will know it and know why without asking us.

    The crimping ring will be correct for the cartridge, taper crimp for autos, roll crimp for revolvers so that's not normally a problem.

    Reloading's really not so complicated, even I can do it! :D

    you will get different opinions. mine happens to fall on the dedicated crimp die side. i just like making sure the bullet isnt going to seat itself deeper or pull itself out. for bolt rifle target shooting i load one round in the rifle at a time so i dont crimp those loads all else gets a heavy crimp.

    I had no problem seating and crimping jacketed bullets in one step for 45auto.
    Cast, plated and moly coated lead was shaving bullets as it was crimping the mouth while it was doing the last 1/16" or so of seating.
    I've gone to using a separate crimping die. The lee factory crimp works very well.
    I'm going back to moly coated soon so I bought a regular redding taper crimp die as the manufacturer advises against the Lee for their moly bullets.

    Oh and welcome to the forum! Stop by the Introduction section when you get a chance BAMonty, and introduce yourself to the rest of the forum :D

    Thanks!!

    I really appreciate your responses. I've been a life-long hunter and am about a year from retiring from the Marine Corps and just now decided it is time to start loading my own ammo - costs here in CA are getting ridiculous!! I am very happy to have found this forum and really am thankful to have your input. Have a good one and Semper Fi!!

    And a Semper Fi to you too, sir. Thanks for filling the ranks of America's defenders.

    Many of the larger military bases used to have specialty hobby clubs for the troops, maybe they still do. Gun Clubs were common and some had modest reloading set ups for members. Maybe your base has one? If so, you can bet the members would be happy to help you get started.

    You dont have to have a separate crimp die but sitting up the seating die correctly to crimp in one step took a bit of time with the lead bullets to not to shave the lead, but if i had read the instruction i would not have had 2000 rd that would only chamber in my 625 S&W long story but i to can learn

    Shoot the reloads in your glock and not only do you void the warranty but you set yourself up for a KaBoom!

    Fuzzball - Please state the die manufactures. I have both LEE and DILLON seating Dies for 9mm & .40cal and neither will not crimp at all.

    Recommendation - A separate Lee taper crimp die works wonders.

    I am not aware of any gun maker that hasn't got a disclaimer in their manuls that say that your warranty is void if you shoot reloads in their guns are you ?

    I have owned guns made by S&W , Colt , Remington , Mossberg , Ruger , Savage , Firestorm , Charles Daly , Taurus , Rossi and Marlin , and in every makers manual all had it clearly spelled out .

    Glocks shoot reloads just great as long as there jacked its the lead slugs that are babe the glock rifleings that are the problem and it dose not take long either, new a guy "still do" that blew up his glock in ten rounds shooting lead

    Taper crimping should be done in a separate operation from bullet seating. Many manufacturers have a taper crimp/seat die. You should not do both operations at once. With some adjustments you can use the same die for the two separate operations. Roll crimping (revolvers) can be done in the same operation (bullets have a crimp groove).

    I use separate crimp dies in the 4th station of my Dillon. As I do not have a separate crimp only die for the .40/10mm, I use the seat die from the .45 ACP set for bullet seating and the crimp/seat die from the .40/10mm set for crimping. I just unscrew the seater stem from this die to turn it into a crimp only die.

    "Fuzzball - Please state the die manufactures. I have both LEE and DILLON seating Dies for 9mm & .40cal and neither will not crimp at all. "

    Please excuse me. I thought my comment, "All handgun die sets I know of..." would suggest to reasonable readers that I don't profess to know everything about all dies made today. (Actually, I still think that. ??)

    Let me be clear: My Lee seaters crimp. I've never used Dillon. I don't bother with minor cartridges and I didn't know what you have until now.

    And even now I'm not totally sure what "neither will not crimp" means. But, it really doesn't matter so I'll give you some slack on that. :)

    Sure, but do they need to?

    There is a magnitude of difference between good liability measures and empirical data.

    All you Kool-Aid drinkers, count your fingers. That tally may be different after shooting reloads.

    [​IMG] it!

    "Glock Kaboom" - 5,980
    "S&W Kaboom" - 1,040
    "Colt Kaboom" - 79
    "Remington Kaboom" - 4
    "Mossberg Kaboom" - 1
    "Ruger Kaboom" - 64
    "Savage Kaboom" - 3
    "Firestorm Kaboom" - 2
    "Charles Daly Kaboom" - 0
    "Taurus Kaboom" - 71
    "Rossi Kaboom" - 0
    "Marlin Kaboom" - 5

    RCBS dies taper crimp for all semi-auto rounds. Revolver rounds are all roll crimped. A good taper crimp is needed on all semi-auto rounds as the pistols headspace off the case mouth.

    Glocks are not to shoot reloads because they have an unsupported chamber. One time you MAY get away with it. The unsupported chamber allows the brass to bulge at the base where you DO NOT want it happening. If you want to shoot reload in your Glock you need to buy a new barrel with a SUPPORTED chamber. The unsupported chamber allows the Glock to function even when extremely dirty.

    Lead bullets have nothing to do with Glocks blowing up. Lead bullets are not to be used in Glocks as well because of the craptastic job they do in rifling them. The polygonal rifling does not provide enough bite to use lead or plated bullets. Look at it this was a jacketed 45 cal bullet for a 45acp is .451" in dia. a lead bullet for 45acp is .452" in dia

    Oh trust me, I have had to decipher all kinds of butchery of the English language. I read police reports everyday that display many of the same characteristics. When I taught report writing, I saw worse. Much worse.

    OK - Please state that you are using "FACTORY CRIMP DIES" - Yes they do seat as well as crimp. But if you want to control the seating of the projectile and then crimp it in place, A 2 step process is better.
