I tried using 10x binos at the 100 yard range, but couldn't see the .30 cal and smaller holes very well.

"Go afield with a good attitude, with respect for the wildlife that you hunt and for the forest and fields in which you walk. Immerse yourself in the outdoor experience. It will cleanse your soul and make you a better person." Fred Bear
