BELLE, W.Va. (AP) — An ammunition company has announced plans to build a factory in West Virginia and add 400 jobs.

Burleson, Texas-based Ranger Scientific said Tuesday in a news release that it has acquired 1,000 acres on a reclaimed mountaintop removal coal mine in eastern Kanawha County.

It says the facility will produce more than 500 million rounds of specialty rifle ammunition each year. The release didn't indicate when the plant would open or how much it would cost to build.

Ranger President and CEO Daniel Pearlson says the company chose West Virginia over six other states.

The company says the plant will mass produce "harmonically tuned" rifle ammunition, which used in Olympic and other international competitions, as well as by experts hunters and in specialized U.S. military applications.
