    38 needs a roll crimp in the base of the canneuler so the bullet doesn't move during recoil. I wouldn't mess with FCD on this.

    If you must it's kind of a feel thing. Just kiss it a little without smashing the bullet any.

    My Lee seater die also roll crimps. Crimp last in a separate operation. Don't seat and crimp at the same time.
    I won’t be wronged, I won’t be insulted, and I won’t be laid a hand on.

    Kinda looks like you're seating .38 Special to .357 OAL.
    Double check your OAL
    The cannelure should be even w/ the case mouth.
    .38's don't need a whole lot of crimp. The one in the middle would be fine.
    Full house .357's want a heavy crimp like the one on the right.
    The object, (as stated above), is to prevent your revolver from becoming an inertial bullet puller and locking up the cylinder.
    Pull those, no harm done, and start over.
    While you're at it.....do be sure you're not using a .357 Magnum load in a .38 Special case.
    That has the potential to be a "Bad Thing"

    Thank you all for the info. I'll be pulling these tonight or tomorrow and starting fresh, using the information you've all given me.

    And yes Mac, they are 38 special loads. 4.3 grains of HP38, they're just on the long side of the OAL spectrum because I wasn't using the cannelure, I was just making sure that they fit within the OAL spec.

    Man. I guess it's true. Crimpin' ain't easy.

    Any particular reason you want the bullet seated that far out? Like oldpink, I think the crimp belongs in the bullet cannelure.
    Where's the Kaboom? There was supposed to be an earth shattering Kaboom.

    Missed your second post last night where you talked about the OAL....my bad.
    Here's the thing......and one of the reasons I detest Lee's manual, they make it sound like you have this huge tolerance to seat your bullet.
    Nope.
    The Max OAL they list is from SAAMI, (the guys that publish specs on all the ammo in the US).
    That's the max length for ANY bullet. They publish that number because anything longer may extend out of the cylinder of a revolver.
    Hollow points need to be seated deeper than Round Nose, and SWC's are generally somewhere in between.

    So what Lee is calling "MIN" is actually where you should be seating it.
    Look at the Hornady Manual.....it lists the COL as 1.450" (guessing 125 XTP)
    That's not a Min, (tho I see why you would thing so after reading Lee's), that's where you want to seat to.

    As a practical matter.....you won't get 'em all to exactly the same OAL. There's too much variation in the bullets themselves.
    I'm generally happy if I keep 'em +/- .005"

    Smile For MOST handgun loads..

    If the projectile has a canna lure or crimp groove, then seat to the upper section of that "Ring"..
    Most revolver style projectiles will have this ring of some sort.
    Pistol (Semi-auto) projectiles not so much..
    For the most part, Revolver loads take a "Roll" crimp.-Rule of thumb, the more powerful the load, the heavier the crimp.
    Most Pistol loads take a "Taper" crimp- Rule of thumb, just enough to remove the "Bell" from the expander die.

    IMO, your projectiles should be seated deeper (To top edge of canna Lure) and your center load in the pic is about right

    Hope this helps...Bill
