10mm Auto - introduced 1983. Derived from the .30 Remington case. Case length 25mm.
During FBI testing in 1988 a reduced-power load was developed to reduce felt recoil to the level most FBI agents found acceptable. Only usable in large-framed pistols and revolvers.

.40 S&W - introduced 1990 as a shorter-cased (22mm) substitute for the "10mm FBI" load, so as to be usable in more pistol designs - specifically the medium-frame pistols currently firing 9mm.

The bullets are identical, and interchangeable (for example, Hornady specifically labels its offerings with '10mm/.400" '.


Neither is to be confused with the 10mm Magnum (31.9mm case length). Introduced in 1992 in the Automag IV. Basically a lengthened 10mm Auto. Uses the same bullets as the .40 S&W and 10mm Auto.

A number of revolvers are set up to fire all 3 cartridges from the same cylinder, moon clips required.


So one could say that those cartridges are the .400" rimless semi-auto version of the .32 S&W Long / .32 H&R Magnum / .327 Federal Magnum!
I have a 3" Ruger SP-101 in .327 Federal so I do know about the different .32s it can shoot.

You mean like my S&W 30-1 (3", .32 S&W Long), Ruger Single Six (6 1/2", .32 H&R), and S&W 632 (3 ", .327 FM)? ;)
Lots of interchange of rounds there... and with my Henry Big Boy Steel Carbine (16 1/2" .327 FM, will fire all 3 above rounds, I've proved it at the range).

Mine is a IMI Baby Eagle in .40 S&W... purchased in 1993. All-steel, baby.

A friend got pissed at me after I let him shoot it, and his first string was a higher score than any he had shot from his 9mm Hi-Power in 4 years of frequent shooting. Amazing what good ergonomic design does for "natural aim-point".
