I am new to this. What is the best way to ID the different models 10, 11, 12, 14, 16, 110, 111, 112, 114, and 116 bolt-actions made from 1959 to the present. I have managed to pick up a few 7 Rem ultra Mag, 338-06, and a SS in 300WSM. What are the possibilities for the different barrel changes? What do I need to look out for in buying stocks for them ? Thank you to all that are helping me.
