How do I make a real life bullet effect?

I've viewed games which mainly focus on competitive, realistic, and fun games, these games are mostly 3Ds, and recently I'v studied Arma 3 and 2's bullet mechanics, which some bullets randomly spreads to another direction by hitting any metallic objects (e.g. Armored Vehicles, Flying Vehicles, etc.)

I've found a video which relates to the topic I am talking about:

(Well basically this video does not hit a metallic object but it's close)

Not sure if you're talking about the ricochet effect itself or the visual effect of the bullet tracing... If it's the ricochet, the bullet behavior does that for you if you select Bounc off solid objects. Here's an example:

If it's the visual effect, there are a few possible approaches: particles, creating "breadcrumbs behind your bullet or even using a line for the bullet instead of a dot.

Hope this helps. Cheers!
