The .224 Montgomery is a wildcat cartridge created by [[IHMSA]] competitor and instructor Tim Montgomery. The case is based on the [[.25 ACP]], necked down to accept .224 caliber bullets, which are typically found in ''rifle'' cartridges like the [[.223 Remington]] / [[5.56x45mm NATO]] and the [[.22 Hornet]].

A quote by Tim Montgomery can be found in Frank Barnes' book "[[Cartridges of the World]]". He says, “I have been shooting this cartridge since 1990, and it is not too hard to get a few sub-MOA groups out of each range session.”

The .224 Montgomery is very similar to the [[.22 Epperson Cricket]], both being a .25 ACP case necked down for .224 bullets. And further, both of these share similarities with the Russian [[5.45x18mm]], all being small pistol cartridges that accept Spitzer-style bullets.

== Ballistics ==

[https://forum.cartridgecollectors.org/t/224-montgomery-wildcat-cartridge/23074/4 Tim Montgomery himself, over at CartridgeCollectors.org forum] discussed a number of loads he's experimented with. For example, "30 grain bullets from [[Berger Bullets]] can be pushed over 2,000 feet per second... but my most accurate loads use 40 grain bullets to about 1600 to 1700 fps."

He fires these rounds from a custom-reamed [[Thompson/Center Contender]] with 12-inch barrel and 1:12 twist.
