What do we know about shot stringing before it leaves the barrel? I'm still guessing that in the old days before shotcups, someone would have experimented with substances that might make shot a bit "stickier" to overcome the effects of gas leakage around the wadding. I'm not talking about opening crimps and dripping candle wax into the shot like us stupid kids used to do in our futile attempts to make loads that really 'reach out".
