Interesting to note that 85 g lead slingshot and 40 g lead slingshot both have similar velocities (m/s):

85g: min. 29.9 avg. 31.2 max. 32.6

40g: min. 29.3 avg. 30.6 max. 32.5

compare .45 acp: (12g) (373 m/s) (835 J)

vs. slingshot: (85g) (32 m/s) (43.52 J)

momentum = M*V

85*32=2720

12*373=4476
