Sir Ron, I am fully satisfied with my CRF Super Express M70 .458 Win Mag and have no desire to aquire a Lott, since the Win Mag is already more than a Lott, and considerably more than a little. Like you, I'm thinking that in North America, a 400 grain expanding bullet will do everything I really need. I have some AA-2230 and new Hornady brass, and I think the new cases deserve a great bullet for testing. I have only a limited amount of these North Fork bullets, and it pains me to shoot too many, since I don't know when I can get more, but I'm willing to develop a load that could work for just about anything.
