Quote:

"In this ancient American sport [which is hunting], the newest thing is a long-range-shooting system that measures distance, determines wind effect and fires high-powered ammunition. These systems turn hunters into snipers by taking the guesswork out of calculating the effects of gravity and wind on a bullet traveling as far as a mile. Applying technical expertise to firearm sighting systems, new players such as Gunwerks and TrackingPoint are winning shares of a market long dominated by venerable brands like Remington and Winchester.

"Long-range shooting is the latest new technology to come to the attention of state wildlife officials, who in various places have limited or banned hunters from using drones, trail cameras and night-vision equipment.

"One factor likely to limit growth is cost. While a conventional deer rifle can be bought for a few hundred dollars, these ultra-sophisticated rifles and shooting systems can cost a few thousand dollars up to nearly $25,000.
