300WSM: matching a factory load
My 300WSM really likes the Winchester Supreme 180 accubond. I can hold 2 - 2 1/4 inch at 200 yds. This year I have been totally unable to find any. After hunting season I am down to my last 15 rounds. They were very spendy to begin with, and nearing retirement I need to reload anyway to conserve re$our$e$. I do reload for my service rifle competitions, so I am not new to the process. I found the factory load was good, and never started reloading for the 300wsm.
I would like to duplicate the load. They advertise 3010 FPS mv. My buddy has chrono his rifle with that ammo at 2950 (Browning Abolt). I shoot a Tikka T3 lite.
I want to chrono that round out of my rifle to get a base to try to get to.
Do I dissect one of my remaining rounds and measure the powder? Anyone know what powder they use? Anyone have a matching load for the accubond?
Thanks in advance
