Many of my older rifles could not be shot unless I cast for them and my modern firearms are way more fun to shoot with boolits because of reduced recoil and noise. But the main reason that I cast for rifles is that I really enjoy the process. I recently bought a pair of Rem Tactical 5R rifles (308 and 223) and installed quality target scopes on them. Neither rifle has ever been fired with a jacketed bullet and probably never will be. Is the cost savings a major factor in casting for rifles? Not really sure. But I love plinking with my Swiss Vetterli and with it's 350 grain boolits cast from range scrap it's cheaper than a .22lr to shoot and very little recoil to boot. I also like being self-sufficient as a caster and not dependent on factory bullets.
