Weather finally broke and I made it to the range on Friday. Shot two new barrels and was generally plaesed with the results. The 270 Ren without any fussing with load printed tight groups with all 90, 100 and 110 grainers. Barrel is a joy to shoot. My 375 Win is a bit of a puzzler. Only shot at 50 yards. The 200 grain Sierra with 35 grains Reloader 7 printed one ragged hole. Tried the 220 and 225 grain Hornadys with the same load and both were wide and inconsistent. Haven't played much with load or crimp. How is the 200 grain Sierra on whitetail ?
