Nosler

The name Nosler applies to a number of companies involved in the manufacture of ammunition and handloading components, specializing in high performance hollow point and soft point hunting bullets. Current companies include Nosler, Inc., Nosler Custom, and Nosler Reloading. Nosler's contributions include both new bullet designs and new manufacturing techniques used in their production.
==Early history==
John Nosler was born 4 April 1913 in Brawley, California. Nosler was hunting moose in British Columbia in 1946, when the bullets he was using failed to penetrate deeply enough to reach vital organs and kill the animal quickly.〔Aaron Carter "John A. Nosler" ''American Rifleman'' January 2011 pp.38-39〕 At the time, most jacketed bullets employed a single copper alloy envelope (the jacket) around a single lead alloy core. The jacket on most military bullets was closed in front and opened at the base. These full metal jacket bullets offered good penetration, but often failed to expand and passed completely through an animal leaving a comparatively small wound. Soft-point hunting bullets like Nosler was using had the jacket applied in the opposite direction to completely cover the base, but open at the nose. These bullets would expand to leave a large wound channel, but sometimes broke into small pieces with inadequate momentum to overcome resistance of moving through bone or muscle tissue.
The experience inspired Nosler to develop a new bullet design, intended to expand readily at low impact velocities yet maintain integrity at high impact velocities (see terminal ballistics). These ''Nosler Partition'' bullets used a specially designed jacket enclosing two separate lead alloy cores.〔 The front core was open on the nose to expand easily, but expansion would stop at the partition (which was a solid layer of copper extending right across the bullet, not just the thin shell of copper which composed the jacket). The portion of the bullet behind the partition has the structural integrity of a full metal jacket bullet, but the expanded forward jacket leaves a larger wound channel. Bullets were originally manufactured for personal use, using hand made, lathe turned jackets. In 1948 Nosler began to sell the partition bullets commercially, forming Nosler, Inc.〔(【引用サイトリンク】title=Partition )
Further innovations by Nosler included new techniques of manufacturing bullet jackets that yielded more consistent expansion, better core bonding techniques to prevent separation of the lead core from the copper jacket, and the plastic Ballistic Tip used to provide the streamlined shape of a Spitzer boat tail, with the expansion of a hollow point.〔 The Nosler Ballistic Tip design has been copied by other manufacturers, such as the V-Max bullet by Hornady. John Nosler sold the production facilities to his son in 1988, and died at his home in Bend, Oregon, on 10 October 2010.〔
