This slingshot target is made from Titanium TC21 alloy, which is super hard and can bear high impact from usual steel ammo. We often saw our shooters posting photos of broken target.
It is always a headache to replace the target, especially in cold weather. The titanium material is much more durable and hard than stainless steel. Not like the rubber target, its character and performance will not be affected by the cold. If you like to hear the impacting on metal or shoot in the winter, this is your correct choice.
