I have a snake problem around the house and shed. These are Brown Snakes and Red Belly Black Snakes which are two of Australians deadliest species.
I'm trying to come up with a recipe for shotshell that will instantly dispatch them but also not go through the tin walls of the shed or have potential ricochet risks.
A few weeks ago I tried 22lr ratshot on a 1.4m long Brown snake but all it did was annoy it. It would've died eventually but we wanted it dead now.
I have ADI AS30N which is the rough equivalent to Clays or Red Dot. I did load up some shotshell with 12gn and rice with cork wads for my buckerette daughter to try out at the range for SASS but wander whether it would be powerful enough to dispatch a snake? These shells did sound very strange when fired, more of a pop not a boom like regular loads. Was it too underpowered for efficient combustion?
Apart from trial and error, is there a rough optimal ratio between powder and load?
