Abstract : It is found that as little as half a metre of foliage, lightly packed at a density typical of such vegetation, will induce vigorous and often irregular precessional motion in the 7.62 mm bullet, the yaw angle in some cases exceeding a right angle. Spaced 13 mm Caneite sheets induce a more regular and predictable precession that might be amenable to mathematical analysis, though much more data would be needed before analysis would be worth attempting. The yaw-measuring technique adopted is found to be capable of giving satisfactorily accurate results; the length of the path over which measurements can be taken is short, and this reduces the value of the data....
