With practice you can break them as fast as he can possibly throw them.
The higher and straighter up he throws them the easier they are to break and yet the more effective they look.
The stop butt should be an iron box with a back sloping downwards, away from you, at an angle of forty-five degrees, deflecting the bullets into a tray full of sand.
Some “numbers” for the programme (range fifteen feet) I give below.
Put a playing-card up edgewise horizontally and cut it in half.
Be sure the background is such that you can see the white edge of the card against it.
If you get your elevation just right, the card will be cut.
Use a .44 calibre bullet in all shooting, as that gives you more leeway in case you are a little wrong in your elevation.
This is the most difficult shot of all and should not be repeated.
The same shot with the card vertical.
