I see a lot of references on the 'net, this forum included, where people specify that they use wadcutters in .38 Spec. in their revolvers for for self-defense. Why use wadcutters for SD? Just wondering.....

I do know that I can get off a second shot faster from my Model 37 Airweight when using 148 gr. wadcutters than when using 158 gr. loads.
