I've got some practice with the T/C single shots and I can reload them pretty quickly, certainly fast enough for a quick follow up shot if I need it. It's just a matter of practice. Having a cartridge holder that fits around your wrist helps a lot. As to "economically", you can easily spend more money than with other kinds of rifles. Those custom barrels are not much less expensive than quality rifles like the CZs or Tikkas. My factory 223 barrel shoots into 3/4". Most other factory 223 barrels seem to do that too.
