.38 bullet ID help please

[Lee T.]

In a box I found of older assorted copper plated bullets were a couple hundred of what I thought were .380 95 gr. But weighing them on my beam scale they're just a tad above 104 gr.
They are .38 of some type....what would these be? Aren't 9mm about 115 g?
thanks for any help, lee

Do you have micrometer, if so can you give exact dimension. What is bullet profile.

[p246]

If. 356 probably. 38 loading. If .365 would be 9 makarov. The bullet profile I have loaded in the Mac was standard RN. The 105 grain 38 was TCFP. I know you said 104 grain but what I have loaded was all 105 grain. I can't remember where I got the plated bullets. I got standard lead through Missouri Bullet Company for. 38

Don't have a mic, only a rudimentary caliper. So the best I can do for dimensions is close to:
cal. .355 "
length .453 "
wt. 104.3 g. average
round nose c.p.
At first it appeared to be a .380 to look at, now I'm pretty convinced it is indeed a .380, just heavier than normal. I've been reading that 100 g was pretty common, so 104 isn't that far off. Either it's a heavy .380 or a light 9mm.
Thanks helping!
