My department is similar to twoxforr.
We shoot 4 times and score once a year(must score 75 to pass).
4X 52 rounds =208 rounds a year.
We are "allowed" 50 rounds a month to use for training. 50x12=600
Only about 5% of officers use these rounds.
About 10% of the officers shoot like garbage (less than 85 score).
About 60% score 85 to 95.
About 30% can score 100 on any given day.
However, Most Police shooting are within 25 feet and alot are within 5 feet.
This is how they survive with little training.
