In the 70's, Leupold sold a very popular target scope called the "Silhouette"... it has short target turrets, and 1/2 minute clicks. It was designed for Silhouette shooting.
I have two of them, and they are fine scopes.
1/2 minute adjustments were common on scopes in the 70's.
The only way to tell, is to shoot a group, dial in 24 clicks, shoot another group, and see if the second group moved 12", or 6".
