Yes, the relativistic mass increase effect can actually improve stopping power under the right conditions.

Here's a gotcha that some hunters don't take seriously enough:

When using a laser sight with a charging target — such as a Texas wild hog — the Doppler shift resulting from the target's closing velocity can actually cause the laser dot to be shifted into the ultraviolet, causing visibility problems for the shooter.

Doesn't happen too often, but hey, knowledge is power.

Texas has some extremely fast hogs!
