I'm also toying with the idea of getting into a big bore rifle, at least for now just for the joy of having such a fine piece of equipment.

If I've followed all of this correctly - A full house .458 Lott will knock my socks off and would be too much gun to start off with as a big bore. However, I could load it down to more managable levels to start. In time I can work the charges up until I'm at full power. Meanwhile, I've only purchased one gun (I'd rather have ten, but there are certain economic realities I must face), and have a cartridge with a plenty of options for reloading. Did I get it about right? If so, I may be a bit closer to picking a cartridge . . .
