The J-frame is the smallest of Smith's revolvers, such as the Model 36 Chief's Special revolvers, the 649, 640 series etc. They are five shot and are in .22 long rifle, .38 Special +P and .357 Magnum.
This is my 649. I have loaded and shot the 170 grain #358429 bullets in this gun and as long as the loads are kept within reason, they shoot just fine and are pretty accurate.
