The .348 Winchester is an American rifle cartridge. It was introduced in 1936, and developed for the Winchester Model 71 lever rifle. The .348 was one of the most powerful rimmed rounds ever used in a lever rifle.
It is excellent for any North American big game in woods or brush, if the 250 grain bullet is used, but not especially suited to long range, as a result of the need to use flat-nose slugs due to the Model 71's tubular magazine.[1] (Factory-loaded, midrange trajectory at 200 yards (180 m) is 2.9 in (7.4 cm) for the 150-grain (9.7 g) bullet, 3.6 in (9.1 cm) for the 200-grain (13 g) round, and 4.4 in (11 cm) for the 250-grain (16 g) slug.)[1] The 200-and-250-grain (13 and 16 g) loadings are preferred for anything past 100 yd (91 m).[1]
In 1962, Winchester dropped the factory 150 gr and 250 gr loads, retaining only the 200 gr. No other rifle ever was ever offered in .348 by Winchester (although Uberti has made some 400 rifles chambered for the .348 in the Cimarron 1885 Hi-Wall in 2005-06), and it has been supplanted by the .358 Winchester (in the Model 88).[1] (The Model 71 was discontinued in 1958.)[1]
