Obsolete Arms and Ammo
By Bob Shell
Apache Junction, AZ –-(Ammoland.com)- In 1888 the British decided that the 577/450 was obsolete and adopted a smaller caliber rifle called the 303 British Rifle.
It was approved in December of 1888 and put into service in February of 1889. The cartridge for the 303 was a derivative of the rimmed Schmidt Rubin cartridge that was a few years older. The Brits went about loading the round in a strange way by using a compressed charge of black powder instead of smokeless which was known at the time though but still quite new.
Like many other countries they adopted a round nose bullet, theirs weighing 215 grains. The velocity of the black powder load was 1860 producing some 1600 FT LBS of energy. In 1892 they changed the powder to cordite still using the 215 grain bullet. That raised the velocity up to about 2050 with a corresponding energy of 2010 FT LBS.
In 1910 they went to a pointed bullet weighing 174 grains which produced 2440 FPS giving 2310 FT LBS of energy. Later on, in keeping up with modern developments in ammunition, they went to nitrocellulose powder. That was the load they used until it was discontinued in 1957 being replaced by the 7.62 X 51 NATO cartridge.
The 303 round and the rifles were very successful and were widely distributed throughout the British Empire. They were widely used in Africa, India, Canada and Australia and to this day are still used for hunting large game. It was the official British cartridge used in WW l and WWll.
The early bullets had a bad reputation for not stopping fanatic natives as they were non expanding. An example is in the late 1890’s the British military took the 303s to the Punjab Providence against the Pushtun fighters. Unfortunately they found that the 303 rounds would not stop the Pushtuns unless shot several times. They brought back the 577/450 on a temporary basis which resolved their dilemma, until a Capt Bertie Clay designed an open point bullet which would expand upon impact.
They were knows as Dums Dums because of the name of the arsenal that they were made at. Later on the bullets for the MARK VII had aluminum or fiber cores which made them longer then normal and they would tumble on impact causing more serious wounds. There were just some many types and variations of the 303 that was used by the military. They included blanks and grenade launcher rounds.
The rifle was designed by an American, James Paris Lee. Since the US did not buy Lee's design he took it to Great Britain and the first rifles were known as Mark 1’s. The deeper Enfield type of rifling replaced the shallow Medford type in 1895. Through out the years there were other similar changes made to all of the MARK models.
There are some authorities who feel that it was the best military rifle of that period because of ease of follow up shots and the 10 round magazine. The 303 British was also rugged and reliable which did not hurt its reputation. It cocks on closing, a feature that I don’t care for but that is my personal opinion. In theory that will help extract an empty casing from the chamber.
There were other rifles and machine guns chambered for the 303 round. Some Martini-Henrys were chambered and can be found for sale occasionally. The Lee Enfield pattern 14 was chambered and used in the world wars to supplement the Lee Medford rifles. Some Ross repeating rifles also chambered for this round. Various semi auto rifles and machine guns also employed this round. There is no sporting rifle chambered for the 303 in the US but at one time the Winchester model 95 was so chambered.
Happily if you want to shoot this gun today, there is some ammo available and components for reloading are no problem. Several companies make brass and bullets. For best results bullets should be .311 or .312 in diameter. The same bullets that are used in the 7.65 X 53 Mauser and the 7.7 Jap can be used in the 303. The case is easy to load and is flexible. Cast bullets can also be used with good results. I have found that the 303 is a very accurate rifle with good loads. For light loads a 32 pistol bullet will work but they would not be suitable for the full powder stuff.

- 46 X AA 2460 125 grain Sierra 2987 accurate

- 44 X 4320 150 grain Speer 2565 very accurate
- 44 X AA 2460 150 grain Sierra 2671 deer load
- Military FNB-80 175 grain 2353 consistent
- Military RAL-64 175 grain 2316 good load
- 48.5 X H 414 180 grain Rem 2441 consistent

In power it is similar to the 7.7 Jap and the 7.65 X 53 Mauser. Some people compare it to the 30-40 Krag but it out performs the 30-40 because it can operate at higher pressures in the military guns chambered for their respective rounds. Some of the later 303’s were rechambered to the 308 round which can operate at about 62,000 PSI which would speak to the strength of the British rifle.
If you are looking for an interesting military rifle that has seen duty in all most every world conflict, the 303 British MK ll Rifle is as good a place to start.
