303 British – 180 Gr PH – HSM Game King (303BRIT4N) – 200 Rounds

The Lee-Enfield served the British Commonwealth through two world wars, and many still hunt with them today. This listing is HSM Game King 303 British 180 grain Pro Hunter ammo, MPN 303BRIT4N, sold as 200 rounds. HSM’s Game King line offers hunting loads for classic calibers that larger manufacturers often overlook.

HSM rates this load at 2,300 fps with 2,115 ft-lbs of muzzle energy. The 180 grain bullet is a heavy weight for the 303, similar to the historic military bullet weight, so many rifles shoot it close to their factory sights. As a hunting bullet, it is built to expand and penetrate on deer, black bear, and hogs at typical woods distances. The moderate velocity suits older rifles and keeps recoil reasonable.

This ammunition fits rifles chambered in 303 British, including the Lee-Enfield No. 1 Mk III SMLE, No. 4 Mk I and Mk 2, No. 5 Jungle Carbine, Ishapore-made No. 1 Mk III rifles, the Canadian Ross rifle, and sporterized Enfields. A common question is whether 303 British and 303 Savage are interchangeable. They are not. The 303 Savage is a different, smaller rimmed cartridge. Another common question is what bullet diameter the 303 uses. Most rifles use .311 to .312 inch bullets, though military bore sizes vary, which is one reason accuracy differs from rifle to rifle.

HSM 303BRIT4N is new production ammunition, not reloads, as indicated by the N suffix. It is loaded in brass cases that work well for reloading. This listing ships as 10 boxes of 20 rounds for 200 rounds total from one lot. A full case keeps an old Enfield working in the deer woods for several seasons, with enough left over to confirm zero every year. Enfield rifles vary a lot in bore condition and sight regulation, so shoot a group at 100 yards before the season and adjust your hold as needed. A few boxes set aside also cover a friend or family member using the same rifle.
