To be honest about it, what would the AI do the standard .280 wouldn't ??? VERY VERY LITTLE..why drive yourself nuts for maybe 200 fps.. I agree with the above, just buy a 7mm Rem Mag if you need that much power or velocity.. usually the simpliest answer is usually best....now if you into competition shooting with it and want the brass to last longer because of the sharp should angle, go ahead..but overall, save yourself the trouble
