I notice on the labeling Magtech 300acc listed blkb the b at the end what does it represent? And are there ways to determine this difference to other loads?

The 300BLKB is the Manufacturer SKU or product #. The OTM by Magtech has a SKU of 300BLKA, while the Subsonic is 300BLKSUBA. I believe this numbering system may be a simple choice of the alphabet, but cannot be certain.
