You landend in longrange shooting heaven! There is a 1000 yard range in Benton city which is within a half hour of Richland, its near the Hanford site. The range is called Rattlesnake Mountain,
http://www.tcsa.info/ . They have a real nice modern range for every type of shooting imaginable. Rattlesnake Mountain holds Palma/F-Class shooting at 800-900-1000 yards which I am particularly interested in. There is also other matches such as 50BMG benchrest, some members told me they are trying to get a bench set up at one MILE! when I was at the big 50 match. I live in Pendleton,OR which is another hour away from TRI-Cities. The next closest longe range is in Baker,OR near the Interpretive center called the Powder River Sportsmans Club. Holding monthly 1000 yard benchrest matches. Vale Oregon which is 11 miles West of Ontario (Oregon & Idaho border on I-84) Two miles South of vale is another 1000 yard range Called the Snake River Sportsmans Club. I shot in my first F-class match there saturday thats pretty much what this range is set up for.
