    The 338 Lapua is also based on the 416 Rigby Case as is the Wetherby rounds, (338/378, 378, 416, and 460)
    The only way to get more velocity with less powder is to increase chamber pressure, some people are shooting the 338 Lapua with 300 SMKs 2900 to 3000 FPS, to do this one only needs to accept the higher chamber presures. I am shooting the 300 SMKs out of my 338 Laupa at 2791 FPS, I have ran them higher but the brass requires a lot more effort to re-size if I do that

    Tim North of Broughton Barrels shot one at the PA World open two weeks ago. He only had the gun three days before the match and still shot well. Black Hills is supposed to be getting 250,000 pieces of brass in sep.

    Big advantage, is same MV or better as the Lapua in a standard mag box!
