I have been working and shooting my current/first build. It started as a rem 700 sps varmint in 308. I was very lucky to bring this gun home a discovered right from the factory with american eagle 168gr. Open Tip Match, and federal match that it was able to shoot 3/4 or better groups. I have now bought a new boyds laminate thumb hole which I have had pillar bedded and a trigger job that got me just above the two lb. mark. I am also shooting a Nkion buckmster 6-18X, that I am very happy with (seems to be very repeatable and clear). I am in the process of replacing the rings and bases for a 20 moa steel bases and rings. I was wondering what are the next best additions or gun smithing that should be done to turn this into a true tack driver. My goal is a 600 yd. hunting/target rifle. Any suggestions would be very helpful, I would like to do things in the correct order.
