Pronghorn live in open country and see danger from far away, so tactics center on terrain and patience.

Spot and stalk
Glass from high ground, then use draws and ridges to close in. Expect to crawl.

Water holes
In hot weather, archery hunters sit in blinds near water.
Decoys
During the rut, a buck decoy can pull in a territorial buck.
Shot distance
Know your range. A rangefinder and steady rest matter in open country.
