Welcome to LRH. It is an addictive place to hang out, ain't it? You're obviously a very good student with some natural ability as a rifleman. Sounds like you've already got a good load going on with that .308 and 178's. You're off to a good start, but you've only touched the tip of the iceberg!.
Next year this time you'll be like the rest of us, selling everything you own, living on the streets, eating outta trash cans just to finance another rifle/build. Sad state of affairs, but it's the nature of the beast.
Good luck and hope to see ya here again on the forums. JohnnyK.
