clay shooting, put the clays at 100 yd intervals in rows and asign each shooter a line then on the go signal they start at 100yds and when that one is broke they move on ( should be easy to 300yds ) the first to finish wins if it's a draw count their brass ,lowest shots wins?
try putting the rounds 20 yds behind the firing point and making the shooters fetch one at a time that will see how they work under pressure and if there out of shape?
how about the courage shot ? put ballons at 100 to 600 yds and then you all pick a range you think you can get a first round hit and see whos most confident in there ability and kit , you only get one shot at each range and if you miss your out? you can either play safe and start at 100 or get a head start by starting further out but remember , first miss and your out!
I did a skill at arms day once for my rifle club which on top of various rifle shooting included knife throwing / spear throwing / dummy hand grenade throwing / archery / we even had a smle grenade cup launcher with nylon dummy grenades and blank rounds , it was great fun !
the only limit is your imagination!
try standing next to another rifle shooter with a clay/ballon each down range at a range to suit your selfs on the word go you drop behind your rifle and load and fire till you pop/break the target, whoever is first wins/survives we call this duelling it's a lot more fun than actually shooting each other!!!! and the winner moves on to the next challenger eventually leaving you with the last man standing.
have fun and above all be safe,
