can you load 380 auto with .357

i have a 380 and i got a really good deal on 400 rounds of .357 jacketed hp.
i know that 380 is .356 but someone told me that you can use the .357 bullets is this true or a very bad idea?

you don't say what bullet weight but the bullets will probably take up too much powder space to accomplish anything in a 380. this probably isn't a place to experiment

If you are talking about using obviously too heavy bullets... and to then add a slightly larger diameter, and shooting them in a mouse gun like a .380, then NO you should not do this, and I doubt you'll find anyone that condones such an experiment.

DON"T DO IT!!! Most 380s have very little case contained in the chanber. The ammont of over preasure you are looking at with the seating depth you would have to hit just to feed them thru a magazine and the very limited charge you already use in a 380, bad things will happen. I think you may be confusing using the pulled bullets in a 38.

Don't go against all reason and fact because a bunch of people on an internet forum tell you to. There are idiots telling people to use shotgun and pistol powder in rifle loads. At least one person is VERY sorry he listened to them.

read ur reloading manuals especially for beginers they are ur bible and properly read and understand the instructions that come with setting up ur dies especially when it comes to crimping.Ive only been reloading for 5yrs now and ive made some very small errors in reloading but because i always went by the manuels i never made any huge mistakes that ruined my guns or hurt me or my wife who shoots with me as well!

Bad idea. The .380 is a very finnicky cartridge, not well known for tolerating pressure changes.

...Not to mention... You didn't say what the bullet weight was. Anything over 105 grains; double the "Bad idea" sentiment.

I am assuming you are referring to this ?

Some of us idiots have had good results loading rifle with pistol and shotgun gun powders, I load 38 spl with Bullseye and there is a possibility of a triple charge so what's the difference ?

That's a good point, jibjab. Especially when considering the topic of this thread: .380 Auto. Many of the faster pistol powders are capable of allowing double and triple charges in the .380. (A cartridge where .2 grains of variation can be the difference between failure to eject and a catastrophic failure.)
