Specifications

The caliber of this model is 7.65mm or 301 inch. The overall length is about 50 inches. The barrel measures 30.7 inches. The rifle weighs about 8.5 pounds without bayonet, the bayonet adding an additional pound.

The arm may be loaded with individual cartridges or may be loaded with 5-rounds directly from the clip. No cut off is provided, but the magazine may be charged at any time by opening the action and inserting cartridges. The rifling is 4-grooves to the right with a twist of 1 in 9.842 iches. The sights are rear notch and front barleycorn. The range of sight graduation is from 500 to 2000 meters. No wind gauge is provided. This rifle is noteworthy also for the introduction of the one-piece bolt with full-forward locking lugs, the strongest system known. The overall length of the rimless cartridge according to Loewe is 3.07 inch, while the length of the rounded-nose cupro-nickel bullet is 1.2 inch. The loaded cartridge weighs about 441 grains. The bullet with a nickel jacket weighs about 229 grains. The original powder charge was 47.4 grains of smokeless but this charge varies in later loadings as powder efficiencies increase. The average standard today is about 42.5 grains to give the same ballistics as the original load.

The muzzle velocity is about 2034 feet per second with a chamber pressure of about 39,400 pounds per square inch. Bullet diameter is .31 inch maximum. (Note: Current loadings for this cartridge, as well as bullet styles, vary with time and place of manufacture).

MODEL 89 BELGIAN INFANTRY RIFLE. RIGHT SIDE VIEW WITH ACTION CLOSED This is the standard rifle officially adopted by Belgium after experimenting with the Model 88 German already shown. Note that in this weapon a barrel jacket is employed which covers the barrel almost to the muzzle. It was designed to protect the hands of the user from heat during firing and to protect the rather thin barrel from injury in field service. The magazine is considerably modified from the earlier design, and is adapted to rimless cartridges.

This is still the basic Belgian rifle, though it is now being replaced. Fabique Nationale in Belgium made this model in quantity. Photograph from original Mauser design records.

Model 1889 Belgian Barrel Characteristics

The barrel of the Belgian Mauser differs from that of most of the others in that externally it is left rough from the turning tool. The barrel is quite thin and its diameter at the breech end is about one-inch greater in front of the chamber and again about the center of the chamber. It is screwed into the receiver in standard fashion.

The particular characteristic of the Belgian Mauser is the thin tube of solid drawn steel which covers the barrel and is intended to protect it and also to protect the hands of the riflemen by diffusing the heat
