I ordered some bullets from gtbullets.com to try out in my Ruger American .300 BLK. They are a 130gr gas-checked HP. Does anyone have a source for .300 BLK data for cast bullets in this range? Looking for supersonic, not sub. I have been loading the 125gr Hornady SST over a max charge of H110 or Lil'Gun with good results, so I'm thinking a lesser charge of either of those would be a good place to start.
Here's the link if anyone's interested:
