In a way, your success is surprising me a little (a lighter grn load of powder) by what I heard some have said, written and claimed to have experienced. But then again it might also be the distance you were shooting.
My rifle is a custom rifle I had built 25 years ago, on a Mauser 98 action, Douglas Barrel, and a Canjar trigger. I built the stock for it.
My rifle did not like 4064, 4895, 4320, and H-380.
But Benchmark and Varget were a different tune... They shot awesome groups, all with the Sierra 55 gn HPBT bullet.
