Like many industries, the shooting business depends on sales. If we are all satsified with that .223 for varmints and the .270 for hunting, reloading components and firearms and all othr associated equipments sales would be pretty slow. However, if you
need a 300 Win mag, and you
need .204 Ruger then the marketeers have money rolling in.
I say this with a smile, because I am a victim of said marketing. A big part of the fun to me is getting a new caliber to shoot and load for. An old geezer can spend literally hours and days developing loads and shooting a new gun.
All part of my personal stimulus plan. Support your local gun shop.
