I am new to this site and to Savage rifles. My first one is on its way to me, and I have many questions. Thanks in advance for any and all responses. My new rifle is a model 11 FNCS in 308. The barrel will be swapped to a heavy barrel very soon. In B/C stocks, which stock will be the right fit for semi L/R shooting 500 under? Is the model 11 a center feed or staggered? I know these are elementary questions, but I know nothing about these guns except they are smoking other brands on accuracy.
