    I have some old fiocchi .380 fmj rounds that appear to have been crimped by the factory. Can these be reloaded? Needless to say, I'm very new to reloading. Thanks.

    Roll crimped? Really?


    Put 'em through your sizer and load away.

    The 380ACP round would not be roll crimped by any ammunition factory.

    Hard to imagine a factory .380 round being rollcrimped since the round headspaces on the case mouth. A picture would certainly be interesting (and added to the list of factory ammo screwups).

    Maybe you are referring to a crimped primer? I can certainly see a factory round having a crimped primer. Those can be reloaded after you swage/chamfer the primer pocket.

    He is talking about the bullet crimp around the base of the bullet.

    Yes, you can reload those.

    Well, if it's around the projectile, it's called a cannelure. IIRC, it's called the same thing if found on the round itself.

    That's not a bullet crimp (doesn't crimp the projectile). It's designed to prevent setback. And yes, they can be reloaded.

    Correct. You can skip the rest of your classes and play floor hockey in gym for the rest of the day, or just go home.

    Now you see why I always suggest that newbs read, read, read and read some more. No one ever listens to me... especially Wisky.

    I couldn't spell canellure. But I can spell lots of other words.

    I've read, on the internet FWIW, that the cannelures on revolver rounds are to identify what load is in there. The old semijacketed HP bullets all look the same regardless of weight. You can't tell if it's a Winchester 125JHP or a 158JHP from the outside. But since I've never seen a guide to how to use the cannelures (legend) I guess it would just be for the factory?:dunno:

    Alright smarty pants... I have ammo cans full of WW once fired brass that Uncle was kind enough to give me. We used to train with 148 grain wadcutters in the Air Force... every one of the cases has a cannelure.

    What say ye now.... hmmm?

    I agree, not enough recoil to warrant extra "crimping" in the middle of the case, and no need to discern different loads since pretty much all full wadcutters are 148 grain wadcutters.

    It's clearly because of the awesome power of the .357 and the .380 that they cannelure it like that.
