This is something that I have never considered until I was asked...
"What is the best .38 Special ammunition that is the
least likely to penetrate walls
and still be effective?"
Is this like going hunting for a unicorn?!?!
I personally don't think there is such a thing, but I guess I could be wrong.
I had a young man ask me that, and all I could think of is that if it won't penetrate a wall, it certainly won't do much to your assailant.
I was thinking about those frangible rounds that I hear about so much, but they can't actually be worth a hill of beans, can they?
I guess I should try one on a game animal to find out...
