Trooper Wrote:The 7mm UIAC is too much like the .280 British (7x43). While I like the 7mm, it does have more recoil (heavier bullet) than the 6.5mm. The one thing that is coming out from my research is that the 6.5mm is at the optimum point among calibers. It has the sweet spot in terms of BC and sectional density. While the 6.5 and 7 are not the best with respect to magnum calibers (too much barrel wear), they are great when comparied to the 7.62x51 or the .30-06. We have the 6.5x55 Swede as the baseline. If we take the .260 Remington (6.5mm-08 with a 140gr bullet) in comparison to the 7mm-08 (162gr) or the 762.x51 (192gr), the 6.5mm comes out strong. It gives similar down range performance with far less recoil.
This whole question would have been moot had the US gone with the .280 British and the FAL back in the '50s!
AND it ALL would be a moot point if we had gone with a .276 Pedersen before WW2!
You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
