Prvi Partizan .303 British 174gr FMJBT — 500 Rounds

The Prvi Partizan 303 British is the military-spec range and competition load in the .303 British category.

A 174-grain FMJBT at 2,460 fps and 2,435 ft-lbs, produced to the Mark VII ball specification that defined the cartridge throughout the Commonwealth’s service rifle era.

At $1.00 per round for 500 rounds, the Prvi Partizan 303 British 174-grain FMJBT is the correct specification for Lee-Enfield owners who want military-weight ball.

The .303 British and the 174-Grain Ball Load

The .303 British was adopted by the British military in 1889 and remained in service through WWII and beyond — chambered in the Short Magazine Lee-Enfield (SMLE), the Pattern 1914, and the L42 sniper rifle.

The Mark VII ball cartridge — 174-grain FMJBT at approximately 2,440 fps — became the standard service load and the reference specification the cartridge is still measured against.

The Prvi Partizan 303 British 174-grain FMJBT matches this specification precisely — modern, non-corrosive, boxer-primed ammunition to the original ball weight.

Prvi Partizan — 95 Years of Eastern European Ammunition

Founded in 1928 in Užice, Serbia, Prvi Partizan has produced ammunition continuously through wartime production, post-war reconstruction, and commercial export.

The factory manufactures centerfire rifle, pistol, and rimfire ammunition across hundreds of calibers for military, law enforcement, and civilian markets worldwide.

For niche cartridges like the .303 British, the Prvi Partizan 303 British is often the most consistently available high-quality commercial option.

FMJ Boat Tail — Application and Platform Notes

The FMJBT is a non-expanding range and target load — not for hunting.

For .303 British hunting loads, the Sellier & Bellot 180gr JSP and Federal Power-Shok 150gr JSP in Related Products are the correct alternatives.

The boat-tail base improves BC over flat-base FMJ for better retained velocity and accuracy at vintage military rifle competition distances.

Frequently Asked Questions

What is the Mark VII ball specification? Mark VII is the British military designation for the standard .303 British service round adopted in 1910 — a 174-grain flat-based FMJBT at approximately 2,440 fps. It replaced earlier round-nose bullet designs and remained the standard British service load through WWII. The 174-grain FMJBT is the specification that Lee-Enfield rifles were designed around; running this weight ensures function and timing match the rifle’s design intent.

Is this safe in a military surplus Lee-Enfield? Yes — non-corrosive, boxer-primed, SAAMI-spec commercial ammunition. Military surplus Lee-Enfields were designed for 174-grain ball; this load is within the rifle’s operational parameters. Inspect your rifle for cracks, erosion, or repairs before use with any ammunition. Non-corrosive primer eliminates the corrosion risk associated with older corrosive surplus military loads.

Can I use this for hunting? No. FMJ bullets do not expand on impact. They are non-expanding range and target projectiles. For .303 British hunting loads, the Sellier & Bellot 180gr JSP and Federal Power-Shok 150gr JSP in Related Products are the correct alternatives.

Why choose the 174-grain over the 150-grain .303 British loads in this category? The 174-grain matches the original Mark VII military specification. For Lee-Enfield owners who want historically correct weight and feel, for DCRA or NRA vintage rifle competition where service-equivalent loads may be required, or simply for shooters who want the traditional heavy .303 British ball experience, 174-grain is the correct choice. 150-grain loads are lighter and faster — different ballistic profile.

Is Prvi Partizan a reputable manufacturer? Yes — founded in 1928, one of Europe’s oldest and most established ammunition manufacturers. PP ammunition is widely used in competition shooting globally and is the primary commercial source for several historical military calibers.

Is the brass reloadable? Yes — Boxer primer, brass case. A notable advantage of PP .303 British over surplus military ammunition, which often uses corrosive primers and non-Boxer (Berdan) priming that cannot be reloaded.

How many rounds is 500? 25 × 20-round boxes.

What’s the per-round cost? $500 / 500 = $1.00 per round.
