I've watched a few of his earlier videos too; he has used .22 to .32 cal and likes the Remington air guns. If I remember .22 is most common because CA law only allows that caliber in some areas. As a matter of fact in some areas CA only allows air gun hunting for any species.
His trash talking is irritating but the idea of killing a turkey with an air rifle fascinates me and now it is on my "bucket list." As far as I know CA is the only place that allows/mandates an air gun for turkey hunting.
Perhaps an air rifle is just the thing for suburban hunting?
If you agree with me call it fact; if you disagree - call it my opinion.
After all - we are talking turkey.
