The .300 Winchester Magnum , and 7.62 × 67 mm, the latest in a series of rifle - cartridges with belt sleeves , which the company Winchester Repeating Arms Company in quick succession from 1956 in his series Magnum brought out. It is a version of the .375 H&H that has been retracted to the .300 caliber (7.62 mm) and shortened to 66.5 mm in length.
history
Introduced in 1963, it quickly surpassed sales of the .264 Winchester Magnum , .338 Winchester Magnum, and .458 Winchester Magnum . Apart from the old .300 H&H Magnum, two other cartridges in the .30 Magnum segment were successful on the market: the .300 Weatherby Magnum and the .308 Norma Magnum . But even these fell behind in terms of sales figures in a short time. The .300 Winchester Magnum is somewhere between the two in terms of performance. All three cartridges are similar in appearance and performance, with the difference that the Winchester and the Norma can be used in normal-length bolt action systems.
The Winchester designers gave the new cartridge the largest possible powder space and accepted a shorter case neck for the bullet, so that longer bullets had to be inserted very deep into the cartridge case because of the overall length to be observed . The case is based on the .375 H&H Magnum belt case .
The bullet diameter is 7.85 mm. The total length of the cartridge depends on the type of bullet and varies between 82 mm and 85 mm. The barrels used for this ammunition usually correspond to the following data: Field dimension : 7.62 mm , draw dimension : 7.82 mm, twist length (depending on weapon): 254 mm (1 in 10 "), number of trains (depending on weapon): 6.
