.256 Win Mag Ammo Prices

Winchester necked the .357 Magnum down to .25 caliber in the early 1960s to build a screaming little varmint round that briefly excited single-shot and revolver shooters. It threw a light bullet very fast and looked like it might carve out a real niche and then the market simply moved on and left it behind. A charming period piece from the age of experimentation.

Factory ammunition is genuinely scarce and priced for its rarity. This leans heavily on handloading. The vintage single-shot and Contender crowd buy whenever the rare boxes surface and reload the rest.
