Introduced with great fanfare in 1956, the .458 Win Mag was essentially a straight-cased and shortened .375 H&H Magnum case, and its 2.5” overall length is better-suited than the .375’s 2.85” is for a bolt-action rifle of reasonable size and weight.

The earliest use of the new round proved somewhat problematic. There were reports of the round not producing the speeds claimed, often leaving the muzzle at under 2,000fps. This was enough to negatively affect penetration, which is a must for a dangerous game rifle round. Some of this had to do because the stated ballistics were with a 26” barrel length, while most of the rifles used for this sort of work used 22”-24” barrel lengths for handiness. Additionally, there were reports that the compressed charges of Olin Chemical’s early ball powder were causing erratic ignition. While these issues were corrected by the early 1970s as Olin Chemical owned Winchester’s ammunition brand and the firearm brand's manufacturing at the time, a certain negativity surrounded the round even though it was by far the most popular round in Africa due to a much-reduced cost of both rifle and ammunition compared to European offerings.

Each box contains 25 once fired brass shell casings. Headstamps are mixed. This is unprocessed brass sourced from commercial shooting ranges. The casings have been washed and polished, but not resized and may still contain the spent primer. It is recommended that all brass be inspected prior to being reloaded and fired.
