Nope, just used the 9mm hp I normally carry. I could believe I'd hit the snake on the 1st shot. It wasn't dead, just had a missing part of it's head. So, I took my time again and hit the second time also. Now, NO head. I figured it was just luck. Of course I was only shooting from about 6 or 7 feet away. I still figured it was just luck.
A couple of months later, I got into the same deal, but, it did take 3 rounds to hit the snake.
BTW, the part about shot cartridges not being reliable is correct. About 25 years ago I only carried 1911s. I wanted to try the shot shells and the ones you could buy were a 1 shot deal-you racked the slide and fumble the case out. I spent about $100 and got a set of dies from Huntington to use cutoff 308 brass to make 45 shotshells. I found each gun was VERY fussy about the load to be reliable. I did find a powder charge that whould eject and load the next round (another shotshell). But, the powder charge would vary for each gun I had.
the reply about a .357 or .44 revolver being about the best trail is right on the money.
