I obtained ten rounds of Hornady 458 Win Mag 500 grain DGS superperformance ammuntion from a friend and with a different friend and his chronograph tested five rounds using a stock 458 win mag Winchester model 70 with a 24 inch barrel (to try and duplicate the barrel length of the Hornady claim basis). The resulting "at the muzzle" measurement duplicated the performance that Hornady claims, i.e. 2140 feet per second. Please note there is currently no 458 Lott superperformance ammunition offering however Hornady claims 2300 feet per second from their non-superperformance 458 Lott 500 grain DGS offering (currently have no 458 Lott so I couldn't test wife's 458 Lott CZ with my friend's chrono).
That is a 160 foot per second difference using a 24" barrel. Here are the Hornady links if anyone is interested:

The Hornady 458 Lott DGS standard ammunition: http://www.hornady.com/store/458-Lott-500-gr-DGS/
Postscript: There is a saying in the semiconductor industry, which may be applicable here: "Process Always Beats Architecture". What this means is that if you make a process improvement (in the case of semiconductors getting more transistors onto a computer chip) it always results in a greater and less expensive performance increase compared to architectural changes (like putting more computer cpu cores in a microprocessor for example). Also note that process improvements take longer to develop than architectural improvements, which happen relatively quickly. The same may be true here. As ammunition manufacturing processes evolve (albeit more slowly, i.e. bullets, powders, primers and shells) they may ultimately beat architectural changes, which happen more quickly, i.e. more powder, bigger shells etc.
Hope this is food for debate.
Cheers.
