Hoppes .30 cal bore snake - Hoppe's 9 BoreSnake Gun Cleaning Kit

There is simply no quicker, easier more convenient way to swab out your barrel after a day at the range. It is so quick that I often will use it on the range every 100 rounds when breaking in a new rifle.
Pros: The easiest way to swab your barrel
Cons: need separate brush for gun mechanism
