Tony and Mike,

Good catch on the shell holder.

While the cost quoted is very high to me, those dies don't show up that often and may be worth it to someone with a 500/450 3 1/4".

Looking at eBay, I see dies for large caliber rifles like 458 Lott and 460 Weatherby for $80 and under and then other calibers for $200 - $300. I guess it is a manner of supply & demand.
