I've been a fan of the .327 Fed. Mag. since its introduction. I like the ultra-high velocity it offers, the flat trajectory and the wicked terminal performance it can deliver, particularly with the 100- and 115-grain Speer Gold Dot bullets that were perfectly engineered for this cartridge.
I'll be taking a Ruger Blackhawk in .327 Fed. Mag. to Africa on a hunt later this year. I hope to shoot one or more of the smaller plains-game species with this pistol, and it will be loaded with Buffalo Bore's 130-grain Hard Cast load. Out of the 5.5-inch-barrelled Blackhawk, this bullet exits the muzzle at almost 1,400 fps. In 10-percent ordnance gelatin, it will not expand, but it will penetrate in excess of 3 feet.
Tim Sundles at Buffalo Bore believes in hard-cast bullets for many applications. They may not be your cup of tea for personal protection, but I'd bet if you were being charged by an ornery black bear, you'd be glad your handgun was full of bullets capable of puncturing its skull and driving very deep.
