Balistic pendulums cannot be upset . by . light . heat . or position ( as long as level ) they are cheap and sturdy . you roll up to the checkpoint on the course . give your rifle to the marshall who has a tin . of 10.6 pellets . he fires three pellets down the tube . thus you have three chances of getting through . same as now .if your gun fails the test . you leave the ground with your rifle . hard but fair ???
