Proof rounds were specially loaded cartridges designed to test the strength and safety of firearms, typically generating higher pressures than standard service ammunition. They were used during factory testing and armourer inspections to ensure rifles such as the Lee-Enfield could safely withstand operational stresses.\u003c\/p\u003e\n\u003cp data-start=\"725\" data-end=\"1064\"\u003eThe MKVI designation places this round in the early 20th century, prior to the widespread adoption of the MKVII spitzer cartridge in 1910. Kynoch, one of Britain’s प्रमुख ammunition manufacturers, supplied both military and commercial markets and is well regarded among collectors for its high-quality production and historical importance.\u003c\/p\u003e\n\u003cp data-start=\"1066\" data-end=\"1301\"\u003eProof rounds are far less commonly encountered than standard ball ammunition, making them particularly desirable to collectors.
