You may be able to use them in your rifle shoots if you have them. That's what we are planning to do. We now use regular clay pigeons as a bonus (similar to an egg shoot) after our groundhog match at 500 meters. The shooters are getting too good hitting the regular clays at that distance.We want to make it more of a challenge.
We don't allow the use of clay birds on our Rifle or Pistol ranges. Now we can only shoot approved paper or metal targets due to some members shooting Bowling pins,Tire's and even Propane tanks. But we do shoot a few in our one manual thrower.
