    My Daughter just bought a 380 Auto & needs some ammo, I reload 9mm auto, with out doing some research can I use 9mm bullets in a 380 auto? I have looked everywhere for some 380 auto ammo, it is very limited like everything else. Thank you guys, LBEE

    Bullet weights are lighter for the .380 than for the 9mm Luger and the bullet profile is slightly different too. BUT, in these hard times if you have bullets you can give them a try and see if they work. I would make a dummy round or two and drop the round into the barrel and be sure the ogive doesn't hit the rifling and the bullet seats completely before I load up live ammo.

    Which bullets do you have and are thinking of using?

    Yes you can but some of the heaver 9mm bullets are too long for the 380, they take up to much space in the smaller 380 case causing pressure issues and can cause feeding issues because they bulge the 380 case where it starts to taper. If you have some 90 to 115 ish grain 9mm bullets you will probably be all right, something like 124 grainer's could cause problems. As always start low and work up your load being aware of the above issues. I load cast lead 105 grain SWC's in my 380, 9mm and 38 without any problems.

    whether or not you can find data for the bullet should be a good hint

    You can, but easily only to about 115gn. There is a fair amount of data from Lyman and Hornady.

    Not sure if you ever make it into St. Charles but Grafs out here has plenty of .380 100gr plated bullets. $10 a hundred I believe.

    They use the same diameter bullet. 115gr. is the heaviest bullet one would use in a .380 and this would be rare. Usually in the 90-100gr. range. Profile of the bullet would be determined by what profile your .380 will reliable feed. All the major reloading sources will have the particular details you will need for a safe load. Good luck

    My daughter & niece like lighter bullets in the .380

    Both my daughter & niece had the same reaction to the more severe muzzle rise with heavier bullets in the .380. They liked lighter bullets. You may get the same reaction out of your daughter.

    If you wanna go heavy in .380, 115-gr is about it. I load them for my BDA, but it's no pocket gun.

    There are 380s and there are 380s.

    Some of mine can do no more than mouse gun performance, while others can exceed 357 mag of the same barrel length.

    There are three levels of handloading published here and there for 45 Colt, 45/70, and 32-20.

    I have my own 3 levels for 380, 223, and 30-30.

    I load .380 weight bullets in 9mm, but I don't typically go heavier than 100 gr. for the .380. Heavier bullets don't profile very well in the .380 and usually require the bullet be seated deeper in the .380 case, thus driving pressures up. And it doesn't take a whole lot of seating depth to have a significant impact on a tiny .380 case.
    Be safe and load what the books have out lined for you as being fitting for .380 or 9mm, and you'll avoid problems.

    I agree with Clark & that is why I asked for more info.

    Thank you

    Thanks guys for your help on reloading the 380 auto, I got lucky Sunday Morning & found some Winchester 380 auto at Wally World for 3.5 Cents each, I cant load them for that so I bought my Daughter 3 Boxes of 100
    which should last her awhile. LBEE

    If you are interested I have 350 Montana Gold .380 95 gr FMJ bullets I could spare. Montana Gold sells them (out of stock right now) for $140 per 1000 and I would offer them for the same price, plus postage. That's $49 for the 350 pieces plus postage $5.80 in a flat rate box. It's not a lot of bullets but I really don't need them at the time if you're interested. Let me know.

    I think he meant 35 cents each. That is about going rate for them.

    I paid $35 for 100 Rounds for the 380 Bullets.

    I shoot 124 Gr. Cast lead round nose sized to .358 in my Hi-point .380. Works great!

    LOL, that's 35 cents a round, not 3.5 cents a round. At only 3.5 cents a round I would want to buy a truck load!! (along with everyone else on this forum)

    I know you said you can't load them at that price but I know I can and for a lot less. You paid 35 cents a round and I can load them right now for 14.4 cents a round. You paid $35/100 and my loads would cost $14.39/100 to make. (well below half the price)
