I set the chrono up at nine feet from the muzzle. It was 63°F and 54% humidity at about 720 ft ASL according to weather.com and the map.
LO: 1049First, that's good consistency. Second, that's crowding the numbers for 10mm loadings from non-specialty manufacturers. Sure, boutique houses like Double Tap or Cor-Bon will load a spicy Ten, and Federal loads a hotter Trophy Bonded hunting bullet, but that's zippier than Federal's own 180gr 10mm Hydra-Shok.
LO: 762.1Note that the fastest and slowest rounds of that ten-shot string were separated by nearly 100fps, and that the standard deviation was nearly double that of the Federal Premium stuff. In case you were wondering what the extra money for premium self-defense ammo gets you, other than fancy bullets, there you go.
Compared to the last .45ACP 230gr FMJ I chronoed in a 5" 1911, this stuff only gives up 10fps, and it's running in a half-inch shorter barrel.
Should we run 2,000 rounds through this thing? Well, we're already 140 rounds in since the gun was last cleaned or lubed, with no malfunctions, so we might as well. 1,860 rounds to go...
