Just my two cents, but I'd go for a Rem 700LTR in .308 before a SOCOM 16. It's a heck of a lot cheaper for one. Second, I don't see a need for a semi-auto in the field. Fluted 20" bbl, good solid action, very accurate (much better than your averageSOCOMs, particularly at the 250 yard range you mentioned), and light and handy enough to drag through fields and brush alike.

But, it's all about what you're looking for. Have fun, and good luck!
