.257 weatherby Mag had a double dose of Blue Dot

According to the story, this guy was reloading, got distracted, and found out the hard way he doubled up.

methodical way of loading ammo. Now semi-auto rifles, shotguns, pistols, ammo loaded for volume, I could see how mistakes could be made. But if you're loading a cartridge for a bolt rifle, precision and consistency should be the name of the game, so every single charge should be weighed, every case measured and weighed, every bullet measured and weighed, I don't see how this could happen. Oh well, not my gun.
