Have to disagree with this comment. Personally I find the FAC air more versatile, that's why it's my go to rifle and why I sold my rim-fires (HMR and .22lr)Anything FAC you have to be prepared to give up if you lose your ticket, so if the land owner sells and your without land your left high and dry facing selling up !
Benefits for me with FAC Air are:
Extended range, with out the fall out range of a Rim-fire
Quarry is put down harder with a real good impact
Nice and quiet
Bucks the wind far better
Already have the charging gear
Ammo: choice is huge, it's not restricted like other FA
