Been running a 112BVSS .300WM in local matches for several years and several barrels. 190 SMK'S at 3050fps sure do shrug the breeze. We can only get to 1000yds here, so maybe he huge advantage of the 6.5s shows up farther out. I have used all the heavier bullets up to 240's but havent needed more than the 190's. BTW its a 27" 1-10 now.
