I have an MP version of the rcbs 45 270 saa with all the pins. I am wanting to work up a deer hunting load with either the penta pins or the deep hp pins. Or maybe the shallower hp pins, but i dont know what BHN to use. I will be using a stiff charge of HS6 or H110 from a .45 SBHBisley and/or a Henry BBS.
