I was perusing the Real Guns archives recently, since I haven't checked them out in a while, and came across an article on the Ruger SP101 in .327 Federal Magnum. The Federal load was quoted as 100 grains at 1500 feet per second. Sound familiar? How about 85 grains at 1400 feet per second (the reduced recoil load)?
Yep, they went and packed the 7.62x25mm Tokarev round into a revolver.
I'm not entirely sold about the effectiveness of such a round in social situations, but now I really want that gun.
