Hey folks. I have a question for someone with better data than I have. Which of these combinations will be carrying more kinetic energy at 400 yds? A 7mm 160gr TTSX launched at 3000 fps,and a .30 cal 180gr TTSX launched at 2750fps? A small skirmish erupted today at lunch time between a 7 RM man and a 30/06 fella. I have some old vague printed material,but nothing relating to the Barnes bullets. I'm thinking it's a shooting match up to 300 yds,then the BC of the 7mm starts to take hold. I kept my opinions to myself,but am curious how it plays out. Thanks all,R.J.
