We have venomous snakes that crawl up the driveway all the way up to the backdoor and lay there in the shade to escape the sun. I was almost bitten once and immediately reached for my waist as I jumped back. If I were to shoot it, what kind of damage should I expect to the concrete and what is the potential for a richochet? What if it was a birdshot instead of a handgun round? I don't think I've ever seen anyone shoot at concrete before so I have no idea what to expect.
