I am in Oregon as well and thinking a free state is calling for me to move. I am a fan of the 124gr Nukes as well. 4.7gr. AC 1.06coal 1070fps. out of a FN509T.
I was using Federal primers and saw some flow around the pin so thought I was getting too close on pressure. Now I realize Federal primers are pretty soft. I had consistent fps just over 1100 with 5.9gr of AC. I have some CCI primers I am going make up some loads with and see if I have the same pressure signs. If not, I will bump my powder up for slightly more fps.
