That's because I helped push the need/desire long-time prior to Blackjack, which then allowed for them to create the Blackjack bullets and be successful, when the time was right, and the market was ripe. The difference is, they're only selling bullets. And their bullets have honest BC numbers. They're not claiming any specific cartridge can do this or that.
If you start a business based on honesty (like Blackjack did), you will go farther in the long-run, than one who ends up being a flash-in-the-pan, and has to come out with something new every other year just to stay relevant.
