I have shot one shot with the .50 caliber and yes must say no recoil compared to a hot load with a 357 mag. I suppose it's the weight but I would also like to get a 454 Casull me and big five did see a nice one at te gun show a while back.

For self defense I carry a Vektor CP1 9mm and it is also very accurate haven't shot anyhting with it yet but on paper it sure prints close to each other.
