You're trying to compare two completely different skill sets with different objectives. Marksmen shoot to kill, usually to eat. Trappers, on the other hand, trap to prevent damage to the pelts, or fur. Trappers use weapons pretty much for protection from unexpected meeting with animals...like bears, or to put down the trapped animal. Trappers don't go around trying to trap humans.....we are just too unpredictable in our patterns, usually. Trappers meet with success by laying traps in runs frequently used by animals....like going to or from water sources.
