GREAT FALLS, Mont. — Campers in Montana's national forests are getting skittish as more sportsmen take advantage of rules that allow target shooting, even though they comply with the rules. The rules bar target shooting 150 yards of a residence, a building, or campsite or developed recreation site. But for some campers, that's way too close.

"If they shoot this way, we're in jeopardy," said John Metrione, a recreation and trails resource specialist with Helena-Lewis and Clark National Forest.
