Winchester

The .45-90 was introduced in 1886. For many decades after its introduction, it was a popular sporting cartridge and is adequate for hunting North American big game. Many gun manufacturers have realized the nostalgic value of this cartridge and have begun to chamber some of their rifles for this load.
