Vickers Shooting Method Targets

The targets are an overlay for an IPSC or IDPA cardboard.
These overlays allow you to use a cardboard target over and over.

This is the best target on the market today.
It is a real value to the shooter as it helps you to aim small, miss small and making your shots count when they matter.

All the trigger time in the world without a proper target will not help you get better.
It is not often that a tool this helpful and inexpensive comes along.
