I strongly believe that an archer shouldn't shot past there known comfort zone. No matter what the situation. However I have known some hunters to take deer at 60 + yrds. Not to mention that pronghorn are routinely taken at these large distances. Keep in mind that at those distances wind is going to affect your arrow fight dramatically. Also the farther the arrow has to fly the faster it looses speed which results in kinetic energy loose meaning loose of penetration. So these things need to be kept in mind when making your choice. The bow will need to be one heck of a strong bow and you'll need to practice practice practice.
