In this blog we examine and test fire Armscor 124 gr FMJ 9mm ammo. We are looking at how it performs and how re-loadable the once fired brass is. Armscor ammunition, located in Stevensville, Montana manufacturers this 9mm ammunition with the head stamp "ARMSCOR USA 9MM LUGER". Their website is www.armscorusa.com. The following information is directly quoted from their web site.

We purchased factory new ammo and examined it. We disassembled one of the cartridges and found that the projectile was a 124.9 grain FMJ brass round nose with a flat base. The brass jacket did not encase the base of the bullet where the exposed flat based lead core was noted. The FMJ bullets were smooth and free of surface manufacturing defects. The powder had irregular morphology with spheres, disks and irregular flakes, and weighed 4.1 grains. The primer was a brass cup and had an internal tripod anvil assembly very similar to a CCI small pistol primer.

We ran the spent cases through a Lee resizing and depriming die and found the brass to move very smoothly through the process without any irregularities in the primer burn hole centering or diameter which adversely affected de-priming. Visual examination of the interior of the case showed a smooth interior cup. The base of the cup was flat and the burn hole had an irregular circular opening due to burrs at its edges. The burs were compressed flat around the lip of the burn hole. Primer seating and fit was snug and smooth with Winchester, Federal, Wolf, CCI, Magtech, and Remington small pistol primers.

Our primary interest is in the reload-ability of the brass. Our initial impression here is also favorable. It is easy to work with. It cleans easily. It runs through our dies easily. It has consistently good seating in the primer pocket of a wide variety of primers. Seating was smooth and firm with each, and did not loosen at all with repeated reloading. The reloads function flawlessly through the test weapon.
We reloaded and fired two cases to failure and found the ANBF (average number of times a case can be reloaded prior to failing) to be 30. As in all other cases tested, the failures were small splits at the case mouth. This ANBF places Armscor in the company of Independence, Sellier & Bellot and Ammo Tech with a solid ANBF (see chart below), but well below Winchester, Aguila and CBC for longevity. Armscor 9mm ammo rates very highly as factory new ammo and the brass was a solid performer for reloading. Armscor brass goes on our “reload with confidence” list with a note about a less than average lifespan.
