Thinking about re-barreling my Savage 116 from 6.5x55 to a 30 caliber. I feel like the 300 wm is pretty hard to beat. I expect this gun will be a typical under 750 yard gun and shorter for hunting. Targets and fun maybe 1000 or so. Am I on the right track? It seems as though the 300 wm like the 308 and 223 is a must have caliber. Also, barrel idea, would like to keep the weight under 8 lbs. I am thinking about a manners thumbhole the MTS-GAT stock. I don't want the barrel too long or heavy, what weight and contour, twist, manufacturer? Thoughts!
