303 British Ammo

.303 British ammunition (also known as 7.7x56mmR) was the Commonwealth counterpart to the .30-06 Springfield before both were replaced by the 7.62 NATO cartridge in military use. Notable guns chambered for this caliber include the Lee-Enfield series of rifles as well as the Vickers and Bren machine guns. Due to its excellent accuracy potential, many hunters still use the ".303 Brit" with soft point loads.

A typical .303 British load fires a 150-180 grain soft point bullet at a muzzle velocity of around 2,500-2,770 feet per second. Most major manufacturers still produce ammunition in this caliber for hunting deer and other midsize game.

The .303 makes an excellent range load as well, with affordable FMJ ammunition available from Sellier & Bellot, Prvi Partizan, and Remington UMC, among others. You'll find a good in-stock assortment for sale here at Widener's so take a look below.

    Each round in this box fires a 174 grain full metal jacket bullet that delivers nice, predictable trajectories. The heavy weight of the bullet provides additional resistance to crosswinds, though it does come at a slight cost in muzzle velocity.

    Prvi Partizan ammunition is loaded in Uzice, Serbia using non-corrosive Boxer primers and reloadable brass cases.

    Looking for some .303 British ammo to keep your rifle well fed? Try this load from Remington's UMC series, which comes in a bulk priced 200 round case for high volume target shooters. These cartridges work well with both Lee Enfields and modern hunting rifles and deliver solid long range performance at a reasonable cost.

    Each round in this case of 200 propels a heavy 174 grain full metal jacket (labeled "metal case" in Remington jargon) bullet to a muzzle velocity of 2,475 feet per second. This is typical for .303 Brit ammo and produces a consistent, arcing trajectory and good accuracy at all reasonable distances.

    Remington UMC ammo is made in Lonoke, Arkansas using non corrosive Boxer primers and reloadable brass cases. UMC (Union Metallic Cartridge) was one of the first manufacturers of brass cased ammo in the US; it was established in the Civil War era.
