Performance
At full potential, the 10mm Auto produces energy slightly higher than an average .357 Magnum load and below standard .41 Magnum rounds. The cartridge is considered to be high-velocity, giving it a less-curved flight path ("flat-shooting") relative to other handgun cartridges. In its lighter loadings, the 10mm Auto is an exact duplicate of the .40 S&W cartridge. More powerful loadings can equal or exceed the performance of the .357 Magnum, and retain more kinetic energy at 100 yards than the .45 ACP has at the muzzle.
Some commercial loadings are as follows:
- .357 Magnum: 676 ft·lbf (917 J) for 180 gr (12 g) at 1,300 ft/s (400 m/s)
- 10mm Auto: 750 ft·lbf (1,020 J) for 200 gr (13 g) at 1,300 ft/s (400 m/s)
- .41 Magnum: 938 ft·lbf (1,272 J) for 250 gr (16 g) at 1,300 ft/s (400 m/s)
The loads listed above are from a boutique manufacturer of high performance ammunition and are about maximum for S.A.A.M.I. established pressure levels in each cartridge. Free recoil energy of the full-power loads listed are 10.1, 12.1, and 22.9 ft·lbf (13.7 J, 16.4 J, and 31.0 J) respectively for these cartridges, computed assuming a 40 ounce (2.5 lb, 1.15 kg) handgun.
Most major ammunition manufacturers offer 10mm loads closer in performance to the "F.B.I. Load" than the full power 10mm; these still contain sufficient power for defense applications, but their recoil is more comparable to that of the .45 ACP in similar guns. However, some companies do continue to offer full power ammunition. With the appropriate load, the 10mm is a capable medium game hunting cartridge at moderate handgun ranges.

Famous quotes containing the word performance:
“Nobody can misunderstand a boy like his own mother.... Mothers at present can bring children into the world, but this performance is apt to mark the end of their capacities. They can’t even attend to the elementary animal requirements of their offspring. It is quite surprising how many children survive in spite of their mothers.”
—Norman Douglas (1868–1952)
“So long as the source of our identity is external—vested in how others judge our performance at work, or how others judge our children’s performance, or how much money we make—we will find ourselves hopelessly flawed, forever short of the ideal.”
—Melinda M. Marshall (20th century)
“O world, world! thus is the poor agent despised. O traitors and bawds, how earnestly are you set a-work, and how ill requited! Why should our endeavour be so loved, and the performance so loathed?”
—William Shakespeare (1564–1616)
