Yeah I know....it’s been beat to death. But I’m curious as to how a case like the 22x47 can achieve velocities with same weight bullets as the 22-250 AI can? Are we running the Lapua case that much higher in pressure to achieve those speeds? Is it that much more efficient? My goal is to run a 75 Berger at 3200fps from an 18” barrel w/ suppressor for a more compact, extended range coyote gun.
