Who could be the manufacturer of this 38 special ammo?

Without some identifying marks or labels there's no way to know who actually loaded it.

In most cases, ammo loaded with Starline brass are hand loads made by small commercial loaders and sold at gun shows and some gun shops.
In other cases, the ammo is loaded by some non-licensed home loader who takes the chance that the ATF won't catch them and charge them with not having a license.

Bottom line, with no way to ID the ammo, it's always a risk to shoot it since you have no idea what, if any standards or care it was loaded with.

Doesn't appear to have much crimp.

Starline

I am minding my own business at a gun show about 3 years ago in Tulsa. Bitteroot Valley is there with a plethora of cheap ammo. I open a box and it was Starline Brass. Based on the price I bought 44, 45 Colt, and some other goodies. The ammo did not perform fantastic but hey I bought it for the brass.

I also bought closeout Ammo from Powder Valley and the company escapes me and when I opened it up it was all starline brass as well.

So several smaller companies have and are using starline. Could be reloads like already pointed out.

Also note the little bubbles on the front of the meplat or bullet nose. Looks like a plated bullet!

Shoot it and reload it! If you really do not like it or do not trust it pull it and reload it.

Have fun!

Plated/reflection

LOL--ok , look like Berry's. Hard to say for sure. If they shoot average you have a good load of brass that will last many reloadings before they are done. Plus the 500 rounds you shoot! Unless you do really suspect them or do not like them.

Have fun!

freedommunitions.com comes to mind,
I purchased some .44 magnum ammo from them last year that looked very similar. Starline brass with a plated fp bullet

If/when you shoot it hold the gun at arm's length and keep a hammer and 5/16" wood dowel handy. And do not practice rapid fire or fast double taps.

Aside from the rather wimpy-looking crimp (explained easily if it is a plated bullet, but I can't tell for sure), it could be one of mine.

It might be a tapered crimp because of the plated bullets.

That bullet appears to be from Berry's manufacturing.
Are you sure that it isn't reloaded ammo?

ArchAngelCD is correct, that's a taper crimp used on plated bullets.

It "could" be from a factory, but not one of the biggies. (Win, Fed, Rem, CCI etc.)

Whoever they were, at least they used high quality brass. That shows some level of care.

It looks too clean and free from marks to be a regular handload, but you never know. If you don't have a box identifying the source, the only safe bet is to pull them.
