I have never had a problem with .22 LR blue topped shot killing a snake from my 6.5" SA revolver.
You have to know that you are shooting a doughnut shaped spread and aim accordingly. Every time I needed to dispose of a snake with .22 LR blue cap shot, CCI I believe, it did just fine, and was very, very effective.
I just aim to one side a little. I don't see why .22 Mag shot if you aim correctly from a rifled barrel would not do the same if not better.
But if using a .22 LR for snake protection. I find that Super Colibri from a 6.5" SA Revolver is quite, and works great for disposing of large vermin and snakes at close distances.
