Tested: Ruger-57 Pistol

With precious few guns on the market chambered to fire it, and even fewer load options for those guns, the 5.7×28 mm FN cartridge has seemingly been on life support for most of its 30-year lifespan, kept alive only through the patronage of a small but dedicated fan club and select military/government agency adoption. That’s a shame, because it’s an interesting little chambering, offering several intrinsic design advantages, and it is an absolute hoot to shoot. Caught in a self-perpetuating loop where a deficit of firearm options has led ammunition makers to deem it unworthy of their finite production resources—and vice versa—what the 5.7 mm has really needed to help resuscitate it was a major gunmaker willing to break the vicious circle by taking a chance on it. That it was Ruger to step up to the plate, with its December introduction of the Ruger-57 handgun, should not come as any great shock to those familiar with the Southport, Conn., company’s reputation for seeing opportunity where others just see risk.

Operating via delayed blowback, the Ruger-57’s barrel moves rearward with the slide only about 1/4″, but its long enough to allow the projectile to leave the barrel and for pressures to drop to safe levels.

Long Range Precision Long Range Shooting and the Coriolis Effect

You may not be taking this into Account in Precision Long Range Shooting
If you’re into long range shooting, its important to understand how the “Coriolis effect” affects your shot at 1000 yards or greater.

The Coriolis effect is the rotation of the earth and the movement of a target downrange from the shooter. This is another element that a long distance shooter has to consider for along with wind, rain, snow, distance, elevation and a many other factors. Accounting for all these factors signifies the skill sets needed for precision long range shooting.

Below highlighted is the simple layman’s term and explanation from Jeremy Winters of Gunwerks, he also demonstrates taking a shot from 1000 yards out to the west and easterly direction.

“if you’re shooting West, your target’s gonna rotate up and towards us, which is gonna cause the bullets to hit lower.”
“if you’re facing east, the target’s going to be dropping and slightly moving away, which is gonna cause the hits to be higher.”
Jeremy points out these small errors can cause huge misses at greater distances than 1000 yards if you don’t pay attention to them.
