Actually I did read that one paragraph.It simply stated that the hi energy loads would give"a tiny edge over factory fodderin kinetic energy transfer and penetration".The word "tiny" is the actual word used in the article.It stated that for tough game like elk this could be worthwhile,It also stated "of course the rounds must shoot accurately in your rifle,or the extra pop is useless".The section about accuracy also stated that the accuracy of these two hi energy30-06 loads did not meet the accuracy standard that the authors had set.Apparently they don't considergroupsin excess of2" at100 yards "respectable",and for that matter neither do I.You speak of 400 yard trajectories,but at 400 yards that 2+" grouptranslatesmost probably to an8" to 9"or evenlarger group,and that is off of a benchrest.Using field positions that group size will grow even larger which will result in not all bullets strikingthe vital zone of abig game animal.That being the case,I will repeat the words used in the article "the extra pop is useless".
