I exclusively purchase Challenger for all of my shotgun needs, its a damn fine Canadian product and its usually cheaper than federal. I'd love to purchase some 7.62x39 made in Canada but its hard for me to justify $1/round when my sks is gonna fling that brass into the abyss and likely leave a nice dent in it, if anyone knows Canadian steel cased non corrosive 7.62x39 options for less than 0.75/rd let me know.
