Re: Elk Anatomy
I went through this same process two years ago. Measured actual elk at different ranges using mil dot thus I knew the dimension of that particular elk precisely.
Went to the field, estimated breadth of a nice 5X5 over a period of 20 minutes. Repeated attempts resulting in 595 yds. Actual laser range was 395.
I suggest getting a good range finder then you know that you know the range.
I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!
