This is an interesting air gun it shoots .45 slugs pretty well at just over 100FPE. But what I was interested in is shooting 12 gauge shot Close range.its done by removing the .45 barrels and using the inner sleve .72 cal / 12 gauge. I've come up with an easy way to make shotshells that are super cheap and can be filled with anything. They stay in place well and are muzzle loaded which tightly holds the load and cap in place until it's shot.
