At the 3-GUN NATION REGIONAL SERIES RULES i have found point 3.3
"Penalties will apply as follows:
- Missed steel beyond 40 yards (static or reactive)=10 Second Penalty"

But in the 3-GUN NATION PRO SERIES RULES is stated:
2.11 Engaging a steel target with rifle, closer than 50 yards is subject to DQ. (rule 8.3)

And in the 3-GUN NATION CLUB SERIES RULES is pointed that round KD plates for the rifle can be placed on the distances from 50yds min till 100yds max,
For the pistol KD plates can be placed from the 7yds till 15 yds and for the shotgun they can be placed from the 7yds till 10 yds.

That`s why my question is:
Is it mistake in point 3.3 of Regional Series Rules, or some exeption for these Series events?

Thank you.

I agree with zbarik, only to add that depending on the area or comp may have set it up different. I would call local place of where you are competing to find out what they have to say.
