I am loading the Sierra 168 gr HPBT Match with 42.2 gr of IMR 4064. It shows real promise at 300 yards - even with a 6x scope, I am holding about a 2" group (well, there are some flyers but they are called bad and are definitely my fault). I am planning to buy 8# of IMR 4064 and 5k or Federal Gold Medal LRP. But I thought I might as well consider some other powders if there is something that is highly recommended. I have tried Reloaders 15 but they don't seem to shoot quite as well. But I am open to suggestions. I have plenty of weight left in my HazMat fee... Thanks Richard Wanna kill these ads? We can help!
