not a high stalk of grass. i have killed bulls and bucks (3 ten point w.tails) with the rocket steelhead 100 but hve seen expandables catch a long stem of grass between the blade tip and point and i have had bulls come by in high grass marshy areas. i loved those rockets but i could see the handwrighting on the wall. the odds are on your side so good luck. me, i never been lucky enough to depend on luck, i required labor, skill, and God's smile to score.
