It's about blast radius and speed. (Destiny)

If you use an exotic primary, this can be a great thing to use instead of swapping guns for heavy ammo to get truth.

Go for grenades and horseshoes, a middle perk to max blast radius or speed if you need it, reload if you don't, and the first should be clown cartridge (free rockets) or tripod (reload not necessary).

With a large blast radius, you can kill people far away. That's why it is good.
