I think the elk shouldn't fall over.
Medium size female elk should be about 500Lbs, or 3500000 grains.
Momentum IS what we use to calculate this so
(135x1270)/3500000 = 0.04
so Elk moves away from the collision at 0.04fps, not nearly enough to make it fall over.

Egghead note - yes I do know that for a perfectly inelastic collision the formula is
m1v1 + m2v2 = (m1+m2)V
but as the mass of the bullet is such a small fraction of that of the elk...
