a-bolt, that Browning ammo was a marketing try of their's in the late sixties. It was tried by the marketing types of one of the many owners of the Browning name. Most of it was sold on closeout at sporting goods stores. Snob appeal was their game, it appears. I acquired a lot of 357 at $5 a box to blast up. No problems with it, just a curio for the headstamp. Packaging was beautiful.
