Hi all.

I'm hoping someone here can advise what the following codes before and after bullets in the AB mobile App Bullet Library mean? Eg:

{PDM} and P(961) for the {PDM} Berger Elite Hunter EOL P(961)?
OR
{PDM} and (A1) for {PDM} Berger EOL Hybrid(A1)?

It gets confusing when you see multiple identical bullets, such as the Berger .308 220gr LRHT, each with a different number after them (39), (59), (76), (848) , etc.

Cheers 👍

PDM = Personal Drag Model, anything after that is so the individual can find their entry.
Given you don't know what cartridge or velocity the PDM was made with they are not what you want to use.
