RL-33 is pretty amazing. My nephew is getting similar results running the 300 Bergers at 3040 fps out of his Edge without a hint of pressure signs. He is getting 0.5 MOA but hasn't finished tweaking the load. However, I have a 338 RUM and wasn't able to get enough RL-33 in the case with the bigger bullets to do any good. I've thought about pushing the throat out but probably won't.
