Quote:You will need higher pressures to get any 6.86 projectiles to keep up with 7.62 NATO. 6.5mm is the caliber node in short actions when it comes to best trajectory, best wind drift, and lower pressures, with substantial bullet weights.:confused: My understanding is that, all other things being equal, it takes higher pressure for a smaller caliber bullet to achieve the same velocity as a bigger caliber, not less.
