Somewhere around here are a couple of threads on practical fighting bolt guns that are pretty informative. Based on the premise that they are useful today, and likely one of the last guns to go given adverse legislation.
Building specific skill sets on those guns seems prudent. On my own to-do list:
Randy Cain's Practical Rifle course: https://guntactics.com/rifle.php
Larry Mudgett's Bolt Action Rifle course: http://www.marksmanshipmatters.com/c...-rifle-course/
