I use Buffalo Bore's hardcast .357 load for woods protection against animals, but I'd rather buy Underwood's ammo for self defense against humans.
Maybe Buffalo Bore will send you a box with Gold Dots, maybe not? Their website has the following disclaimer, "Please note that photographs may differ slightly from actual product." So if they send you a box with Montana Gold bullets then you just wasted your money.
Besides, here is a comparison...
Buffalo Bore .357 mag, box of 20 JHP's = $27.94 + shipping
Underwood .357 mag, box of 50 JHP's = $28.17 + shipping
