Any Weatherby Mark V is a work of art, and your should be no different. Typically, they shoot OK, just not fantastically well, due to the thin barrels, expect about 1"-1.5" at 100 yds. I can only say the muzzle blast from 257 Weatherby will surprise you, just be ready for it. On the plus side, the 257 Weatherby shoots about as flat as a string. Congrats!!
