Category C (semi auto .22LR + miss-categorised shotguns) is for farmers.
Category D (centre-fire semi auto + miss-categorised shotguns) is for specialist pest controllers.

Professional hunters tend to use Category B (manually cycled bolt/lever/pump centre-fire).

You’re not wrong, I just wanted to add more info.

There’d be like a thousand people that qualify in the entire country for a real Category D.

nationalsecurityjournal.org looks like a propaganda outlet.

How do you even check the bonafides of a random site like this?
