Nosler Trophy .243 Winchester ammunition (part no. 61046) loads a 100-grain Partition for hunters who want dependable performance in the field. Nosler is best known for the bullets serious hunters trust, and it loads those same projectiles into its factory ammunition. A dual-core design keeps a front and rear lead core separated by a solid partition wall, so the front expands while the rear retains weight for deep penetration. Cased and 20 to a box, it is built to feed reliably through bolt guns and semi-autos chambered for the cartridge. In our rifle ammunition lineup, this .243 Winchester loading is a dependable choice worth adding to the cart.
