Note: also posted on Ammosmith and Cast Boolits. I was just watching the sniper rifle episode of ultimate weapons (2009), and they (Tactical Rifles' Rep) were comparing the 6.5x47mm to the 308. I thought it might be interesting to hear some discussion about this. To be clear, I am not LEO or military, and my only experience with a 308 is from a mil surp rifle several years ago. My interest is mostly academic with some chance of reloading in the far future. They were firing it from Tactical Rifles M40-T7. Edit: could a mod correct my title please? 6.5 not 6.4 sorry.
