your question has Remington 7600 in 7-08 or 243 written all over it. But if you want a sweet little carrying rifle, you could stick with the bolt and try the Ruger Compact, Remington Model 7 or Browning Micro Hunter in .243, .260 or 7mm-08.
How often do you need a fast follow-up shot. The pumps are nice but a bullet is like a business. It all boils down to location, location, location.
