Swiss Military 7.5x55 GP11 ball ammunition. This is some of the finest quality ammunition ever produced. Extremely accurate, reliable and non-corrosive. Mostly made in 1982, but possibility of other years of production. Comes 10 rounds per box, 6 boxes per brick 8 bricks per case. The Cartridge features a brass case and Berdan primers and Cupronickel jacketed bullets with lead core. Cupronickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese and is magnetic so a magnet does stick to the bullet. Bullet weight per the importer is 174 grain.

The GP 11 cartridge
Swiss Army issue 10-round GP 11 pack.

In 1911 the metallurgy and bolt design in Swiss military rifles had advanced enough that a more powerful cartridge could be used in the Model 1911 rifles and Schmidt-Rubin 1896/11 rifles. The 7.5 mm Swiss round was updated to the completely non-corrosive Gewehrpatrone 1911 (GP 11). Besides being used in the Model 1911 rifles and Schmidt-Rubin 1896/11 rifles, GP 11 ammunition was also used in the MG 11 machine gun, K11 and K31 carbines as well as in the Stgw 57 battle rifle. The cartridge saw extensive service until the early 1990s with the standard rifles of Swiss servicemen, and still sees use by Swiss Army reservists, and sport shooters, of which there are many. Furthermore, it is still the standard ammunition for the MG 51 general purpose machine gun used on many Swiss armored vehicles such as the Pz 87 "Leopard 2" tank or the MOWAG Eagle Reconnaissance Vehicle. In this role, it is usually belt fed with GP 11 full metal jacket and GP 11 tracer rounds.

The 11.3 gram (174 grain) Full Metal Jacket GP 11 spitzer bullet offered good aerodynamic efficiency and ballistic performance with a ballistic coefficient (G1 BC) of 0.505 to 0.514 (ballistic coefficients are somewhat debatable). At 780 m/s (2560 ft/s) muzzle velocity the standard GP 11 ball bullet retained supersonic velocity up to 800 m (875 yards) (V800 ≈ Mach 1.1) under ICAO Standard Atmosphere conditions at sea level (air density ρ = 1.225 kg/m3). Even by contemporary (2007) standards 800 m (875 yards) typical effective range is quite remarkable for a standard military rifle round.[2]

GP 11 is regarded as highly accurate and well-manufactured ammunition. Due to the increased availability of K31 rifles on the civilian market, a number of cartridge manufacturers, including Prvi Partizan and Hornady, now produce 7.5×55mm rounds in full metal jacket, soft-tip, and ballistic tip configurations.

In addition to the standard Full Metal Jacket GP 11 rounds, specialty rounds were produced as well. Armor-piercing steel-cored rounds can be identified by their violet bases. These rounds can easily pierce 5 mm (0.2 in) of steel plate at 500 m (550 yards). Tracer rounds burn out to 800 m (875 yards), and can be identified by their red tips.[3]

Despite its nomenclature, the 7.5×55mm Swiss can with proper care use the same 7.62 mm (.308 in) bullets as conventional Western 7.62 mm (.308 in) cartridges that have slightly wider land and groove diameters. This allows for ease of handloading and custom competition or hunting loads, as nearly any .308 diameter bullet may be used. However, most Swiss match shooters use standard GP 11 ammunition, a testament to the accuracy of the GP 11 round.

The Karabiner Model 1931 (K31) is a magazine-fed, straight-pull bolt-action rifle. It was the standard issue rifle of the Swiss armed forces from 1933 until 1958, though examples remained in service into the 1970s. It has a 6-round removable magazine, and is chambered for the 7.5x55mm Swiss (also known as Gewehrpatrone 1911, GP11, or unofficially 7.5x55mm Schmidt Rubin), a cartridge with ballistic qualities similar to the 7.62x51mm NATO/.308 Winchester cartridge. Each rifle included a 6 round detachable box magazine with matching stamped serial number. A charger is used to load the magazine from the top of the receiver.

The often quoted but incorrect name of "Schmidt-Rubin" comes from two designers: Rudolf Schmidt, who designed the action for Switzerland's 1889 and 1896 rifles, and Lt. Col. Eduard Rubin,[1][2] who designed the ammunition.

Although the K31 is a straight-pull carbine like many other Swiss rifles, it was not designed by Rudolf Schmidt (1832–1898) as he was not alive to do so. The K31 was a totally new design by Eidgenossische Waffenfabrik in Bern, Switzerland under Colonel Adolf Furrer, and the gun does not have the Schmidt-designed 1889 or 1896 action. The first 200 K31s were made in May 1931 for troop trials (serials 500,001 - 500,200), thus the model number of 1931

I wish I had ordered more before it sold out. This is the best surplus ammo you can buy. My K31 will get 3/4 inch with it if I do my part. SGammo is the only company I order from now, shipping is fast and they always seem to have what I'm looking for.
Hopefully there will be more - immaculate condition - very well packaged (and sealed) by the Swiss. Waiting on my K31 but have no doubt this will perform flawlessly Delivered in 3 days from ordering - VERY impressive - this is my 3rd order from SG and will be back for certain! Thank You
I recently bought a case of this GP11 for use in my swiss K31 rifle,this is without a doubt the best surplus match grade round you can buy! My case was dated around 81 and was in excellent condition, stock up now before they are gone! SG ammo has the best prices and great service!!! thanks guys
It was my first time ordering from SGAmmo,so I did not know what to really expect. My order was processed and shipped very Fast. Excellent service and communication. Best deal on Swiss 7.5X55 that I could find. I will order from SGAmmo again.
I absolutely love this round, wish I could afford 4000 rounds of it! Regardless it is worth every pennY.
Ordered today from SGAammo and 4 hours later I already have a UPS shipping label created. This company is fast and dont play around. They send your order right out. The case of 7.5x55mm swiss ammo is the best price around. I have ordered a while back from SGAMMO AND I'm very happy with them. I will continue to order from this company. Thank you .
I'm HAPPY, I created an account at 7:55am, spent an hour checking every other site that list GP11 (7.5 X 55) ammo. Best price and shipping cost is here.,, ordered a case 480rds. at 8:57am I got an E-mail my order was complete, at 4:27pm got an E-mail with UPS tracking number,, I order a lot on line, this is the fasted service I've had. I'll return many times
More or less what it says on the tin. 26.10.82 production as stated, topmost 60 round packs were a little dirty, having probably been scuffed against the top of the box for the past thirty-some years. Rounds themselves are in fantastic condition and shoot about as well as any modern match ammo could.
This is excellent ammo at an excellent price. After my first purchase I ordered more. I was surprised at the pristine condition of the ammo as it is in better condition than most current year ammo. This indicates to me quality manufacturing. Also note that this is very clean, non corrosive ammo.
My 480rd case arrived today in perfect shape. 1982 manufactured as requested. Good deal on match grade ammo for my K31. I plan to order again. Thanks
