Hey Marty. Want youre head to spin a little more. In the great State of Colorado no cal 50 round balls for Elk. But you can use a 40lb bow to sling some sticks at one.
Hey
BigAl52. Want your head to spin a little more. Check out these numbers on sectional density :arrow:

Density is purely the relationship between bullet weight and bullet diameter, and is independent of bullet shape. All else being equal, in theory the higher the
Sectional Density value the greater the bullet penetration on game. (i.e., a 150 grain, .270 caliber bullet will provide better penetration than a 150 grain, .30 caliber bullet.)
Never underestimate the traditional bow. My traditional wooden arrows weigh 540 grains. Using my arrow shaft(11/32") diameter at 0.34375...
the Sectional Density of the arrow projectile is
0.653.
