OG-15G1 is the projectile while OG-15BG1 is the complete round with the PG-15P propellant cartidge
Bulgarian, but there is very little difference only

Yes, most certainly Bulgarian and not Russian. The original designation in the brochure's text may be incorrect (a typo), or something different (see later text).
A round of ammo, in standard nomenclature, would be OG-15VG1 (ОГ-15ВГ1) and not OG-15BG1 (ОГ-15БГ1) as per the brochure. In standard nomenclature the 'V' (В) is short for the word for a round of ammunition; as per the text 'Vystrel' (Выстрел). It could be the case that the 'B' (Б) is short for Bulgaria (България), but I'm sceptical.
The projectile component for this round of ammunition is the OG-15G1 (ОГ-15Г1). The propelling charge assembly's base designation would be PG-15P (ПГ-15П), but this can change. It can change if components within it are different, either due to being modified for various reasons, or to accommodate a different projectile.
