Been pulling my hair out with this rifle, so as a result, I ordered the new 110 in .338 Lapua! Makes sense doesn't it? With that said, I have seen the Bas 10 punch nails at 100 yards and group in at 2" at 400 yards. With mine, I can ping 14" steel at 800 and even a 1000 yards but can't group worth a rats a$$ even at 400 yards. Have tested: IMR 4895, 4320, 3031 Reloader 15 & 17, Benchmark, Varget, N150, 540 & 550. Use Sierra 168 BTHP/175BTHP & Hornady 168 BTHP. Have started with min load and worked up to max in .5 increments. N150 and R15 have yielded the best results with either/or the Sierra or Hornady 168 BTHP Match bullets but still fail to score a decent grade on paper. Even shooting in a custom rack in no wind, I'm sure it's me but does any one have any other loads they could recommend?
