These are really nice if you want to take a break from the HADES and jumbo heavy's, to get more penetration out of your shots for those tougher birds that always seem to magically deflect one's pellets.

From the manufacturer's website;

"Characteristics: The right choice for real hunters (if allowed in the country). Pointed profile for better penetration.

This lighter variant is suitable for most commonly available air weapons of lower to medium strength.

Muzzle velocity when setting the weapon to 16J: 175m/s.

Do you want to experience a little action and adrenaline of a real hunter? Our Stratons have pointed heads that give your projectile the required penetration. Enjoy the feeling when you hit exactly and destroy your target, whether it is a ceramic pigeon, a tin squirrel or a paper rat. Stratons are also popular for pest control (in countries where this is permitted by law). I work very well from most main and at different levels of muzzle velocity settings."
