I load with a stiff charge of H110, (same as Win 296) and get about 1,370fps. for 1,000 try 13 grains of 2400. Blue dot would probably be a good choice but I can't find a load right now. I like loads in the 1.000/1,100 fps. range. My favorite load pushes a 240 swc at about that speed and it is fine out to 100 yards. You don't need a gas check at that speed.
