I will be making another trip to my cabin property in the near future. I am going to bring some reloading equipment with me and give this duplex load technique a try. I never did buy the wc872 so I will likely use the wmr ball powder instead. For the kicker charge, I'm going to use imr4227. I will start at 1 grain of imr4227 then fill case with WMR. 77gr bullets will be tried first. I will work up the kicker charge of imr4227 until the rifle cycles, burns clean or I start to see pressure signs.
My plan is to use a standard carbine gas AR15 and will use the ability of the rounds to cycle the action or not as my guide to success. Of course I will also watch the brass and primers for pressure.
Next attempt will be to try this in 308 bolt rifle.
