This totally sounds like cookie clicker but with bullets instead of chocolate chips... lol here's some AIslop based off the concept, i really like the spirit of the meta here:

"Every click makes a bullet; every upgrade makes the world slightly worse and your numbers way bigger. Overtime as you make progress in the game, the world just gets way worse as your RPMs go up. You start out as an artisan small shop of some sort, casting each and every bullet by hand with loving care and passion.. (You, the handloader an artiste!) Then, as you become a soulless corporation and have an army of factories, and finally you become Skynet and the whole thing is automated. GG"

This whole concept just seems perfect for a clicker game to begin with. Thank you AI!
