Thread: Seriously underrated 6.5x47 Lapua

Purely in terms of practical physics, as I think gas discharge creates more thrust into your shoulder (by working exactly like a thruster) then the saum would have to have less recoil, as in order to get higher velocity, all else being equal, it needs to make better use of the powder charge.

In other words, more efficiency means more energy transferred to the motion of projectile and less to the rifle.
