For what it’s worth I’ve had good luck with 59 to 60 grains of Reloader 15 under a 250 gr Nosler BT (discontinued) or Accubond (current). The WLR works fine as a primer. I have also used the WLRM with near identical results. No issues in either of my guns. I get 2500fps out of my Krieghoff drilling and 50fps less out of the Merkel DR. Flat shooting good deer whacking load.
