I was shooting a .380 today, I had both Remington and Winchester ball ammo on hand, both claim identical ballistics - 955fps at the muzzle.

Remington ball looks decidedly vintage, whereas Winchester ball has a flat metplat profile. Winchester also lists the ballistics right there on the box, Remington just lists a website.

IIRC 50 rounds of Winchester was like $30 at Academy, Remington $29. From here on in I’m going with Winchester.
