Useful books for improving marksmanship

[Twisted300Win MAG]

As the title states I'm looking for suggestions on books that would prove helpful in improving marksmanship ie form fallow through shooting on call exc. I realize practice makes perfect, believe me I shoot as much as time and money permit. I consider myself to be an average shooter and I'd like to improve.
Thanks
Donald
