I kinda view the .52 like a wildcat cartridge in the centerfire world. They perform admirably for the purpose they were intended. Probably better than the average person who has never tried them will ever understand. The .52 is kinda the same way in my opinion. The majority of shooters will probably never buy a .52 just like the majority won't ever use a wildcat cartridge but those who do will probably not give them up and will be extremely satisfied with their performance once they experience it.
