I've had this rifle for just over a year and I love this thing, but its a testament to all rifles are different. A hot load (32.6 varget) in my brx isnt near what most seem to use but in mine the 32.6 gives ejector marks. I've learned to load test at 300yards cause anything closer every load is pretty much the same, and that the rifle likes to be shot dirty (200+ rounds without cleaning). I just don't understand why at 300 the Sierra 107s group at 3/4", and the bergers are between 3/4 and 1" but at 500-1000 the bergers are a lot better. I don't have specifics on group size but the scores are better with bergers.
