God willing there is always a tomorrow and you can give the matter plenty of thought and look at whats out there in the meantime.

Another expense with the conversion to 500 you considred and that I failed to mention was not only open up the bolt face but also widen the magazine box and feed rails to take the fatter case, in some rifles this expense alone would prove too great to warrant the exercise hence your plan to sell the rifle and buy a .500 outright.

Seriously do look at the .458 Lott or even a CZ Amercian in .505 Magnum (Gibbs), with some after market work to stock reinforcing these rifles work well and offer better cost option than making a rifle not designed for .500 into such.

Again just my thoughts
