I do a lot of casting... we do what is called 'low node' ... typically 800 to 1200fps. I have a fav load with 200gr plain base cast and it makes bugholes at 50 with a 308....
Another forum I am a member of a guy is posting some of his experiments with reduced loads for .308 Win - and getting some pretty impressive results - Specifically with one of his loads using 8.5 grains of TiteGroup and 190 grain bullets at about 1100 FPS.
