They usually show brand, such as SIE (Sierra) or HDY (Hornady) or NOS (Nosler).
Besides which, brand doesn't matter if you're using a bullet of the same weight and similar construction, such as traditional copper jacket, lead-core bullets. There's only so many ways to make a .308 caliber lead-core, copper jacket bullet that weighs 150gr, for example. They're close enough to interchange data, so long as you start low and work up, like always.
Still happily answering to the call-sign Peetza.
