Ok after reading the thread is a battle rifle needed and seeing all the discussion on this topic the thread is based on, I want to post this https://www.pica.army.mil/Picatinny...6mm_Enhanced_Performance_Round, 1960-2010.pdf unfortunately I am not seasoned enough on this forum to be able to post in that forum topic but thought that it would fit in here and this is a topic realted to the thread where the last discussion wasnt. I think that this is a very accurate study stating that there are advantages and disadvatanges to the two calibers. Its a long winded report but worth it! Wanna kill these ads? We can help!
